1. Introduction

1.1 Data sources

The ‘Arrests and outcomes’ section contains data provided by the Counter Terrorism Policing Headquarters (CTPHQ) Coordination Centre and includes statistics for Great Britain on the:

• number of arrests for terrorist-related activity and outcomes (such as charges and convictions) following such arrest
• number of charges and convictions broken down by legislation used
• sex, age, ethnicity, and nationality of those arrested, charged and convicted

The ‘Court proceedings’ section uses data from the Crown Prosecution Service Counter Terrorism Division (CPS CTD) and includes statistics for England and Wales on the:

• number of persons proceeded against by CPS CTD for terrorism-related offences
• number of persons that have been prosecuted and convicted, broken down by the legislation used

The ‘Terrorist prisoners’ section uses data from His Majesty’s Prison and Probation Service (HMPPS) and the Scottish Prison Service (SPS) and includes statistics for Great Britain on the:

• number and ideology of persons in custody for terrorism and terrorism-connected offences
• ethnicity, nationality and religion of those in custody
• number of persons released from custody by sentence length

The ‘Other police powers under TACT 2000’ section uses data provided by the MPS and CTPHQ, and includes statistics on the:

• number of stops and searches carried out by MPS under section 43 of TACT 2000
• number of stops and searches carried out by police^{[footnote 1]} under section 47a of TACT 2000
• number of examinations and subsequent detentions made in Great Britain under Schedule 7 to TACT 2000
• data on goods examinations, strip searches and on refusals of requests to postpone questioning (usually to enable an individual to consult a solicitor) under Schedule 7 to TACT 2000

The user guide provides further details on this release, including the strengths and limitations of the datasets, and the quality assurance processes involved in the production of this release. It also includes a summary of the criminal justice process, a glossary of terms used, the legislation and the categories referred to in this release.

1.2 Main changes and additions to this release

There have been changes in the data presented within this publication which concern:

• the legislations ss. 54 and 56 under Terrorism Act 2000 were previously grouped together with the description ‘weapons training’. Now the legislations have been split into Weapons training (s.54) and Directing a terrorist organisation (s.56)

Users should also note that an update to the breakdown of data for terrorism-related offences by sentence lengths for defendants tried and convicted by the Crown Prosecution Service is excluded within this release as this data is currently not available to the Home Office. The last update was provided to the Home Office for the year ending March 2024.

The main changes and additions to the Bulletin are presented in detail in Section 6 (About these statistics) under ‘Section 6.3’ ‘Main changes and additions to the bulletin’.

2. Arrests and outcomes

Main results

• in the year ending 30 September 2024, there were 245 arrests for terrorist-related activity in Great Britain, 71 more than the year ending 30 September 2023 (a rise of 41%) representing an increase of 28% over the latest 5-year median (191) and a fall below the historical 10-year median number of arrests (254)
• at the time of data provision^{[footnote 2]}, 88 arrests resulted in a charge (36%), of which 70 were for terrorism-related offences
• of the 32 individuals arrested under section 41 of TACT 2000 in Great Britain, there was one instance where a request for access to a solicitor was delayed

This section presents statistics on the number of persons arrested by the police in Great Britain where there was suspicion of involvement in terrorist-related activity, either at the time of arrest or at a subsequent point in the investigation. In some cases, evidence may emerge after an arrest for a terrorism-related offence that suggests a suspect does not have links to terrorist activity but has committed a non-terrorism-related offence. These cases are included in the data as non-terrorism-related charges and/or convictions.

Outcomes following arrests for terrorist-related activity are also included in the statistics, which show the number of arrests that led to a charge or prosecution as well as other outcomes. Demographic information about those arrested, charged and convicted is also provided in this section. All data in this section is based on the date of arrest. This allows users to see the outcomes of all the arrests in a specific period (such as how many led to a charge and conviction).

As cases progress over time, figures published in this release are likely to be revised. This is particularly relevant for more recent time periods where a larger number of cases will not have been finalised (‘released on bail’ or ‘awaiting prosecution’). The effect on the arrests total will be minimal but the number of charges and convictions currently reported will likely increase in future releases, especially for cases from the more recent quarters where a greater number have not yet reached the point of charge or conviction.

Data is provided to the Home Office by the CTPHQ Coordination Centre and is taken from a live database. This section includes annual breakdowns of the data from 11 September 2001 (when the data collection began) to the year ending 30 September 2024, as well as quarterly trends over the most recent 9 quarters. The data was based on the latest position of each case as at the time of provision to the Home Office (on 29 October 2024).

A flow chart summarising this section is included in Figure 2.1. The flow chart is designed to show how individuals who are arrested for terrorism-related activity are dealt with in the criminal justice system. It follows the process from the point of arrest, through to charge (or other outcome) and prosecution. The annual data tables from A.01 to A.13b include data on arrests and outcomes and are provided alongside this release. The data is broken down by rolling years to September.

Notes:

1. Based on time of arrest, between 1 October 2023 and 30 September 2024.
2. Data presented is based on the latest position with each case as at the date of data provision from CTPHQ Coordination Centre (29 October 2024).
3. ‘Alternative action’ includes a number of outcomes, such as cautions, detentions under international arrest warrant, transfer to immigration authorities. See annual data table A.03 for a complete list.
4. Terrorism-related charges and convictions include some charges and convictions under non-terrorism legislation, where the offence is considered to be terrorism-related.
5. The ‘other’ category includes other cases/outcomes such as cautions, transfers to Immigration Enforcement Agencies, the offender being circulated as wanted, and extraditions.
6. Cases that are ‘awaiting prosecution’ are not yet complete. As time passes, these cases will eventually lead to a prosecution, ‘other’ outcome, or it may be decided that the individual will not be proceeded against.
7. Excludes convictions that were later quashed on appeal.

In the year ending 30 September 2024, there were 245 arrests for terrorist-related activity in Great Britain, 71 more than the year ending 30 September 2023 (a rise of 41%). Of the 245 arrests:

• 88 were charged, 50 were released without charge, 7 had alternative action, 99 were released on bail to return and released under investigation, and one has a decision pending
• of the 88 charged, 70 were charged with terrorism-related offences, and 18 were charged with non-terrorism related offences
• of the 70 charged with terrorism-related offences, 23 were prosecuted, 42 are awaiting prosecution, 2 had other outcomes, and 3 were not proceeded against
• of the 23 charged with terrorism-related offences and prosecuted, 22 were convicted of terrorism-related offences, and 1 was convicted of a non-terrorism related offence
• of the 18 charged with non-terrorism related offences, 5 were prosecuted and 13 are awaiting prosecution
• of the 5 charged with a non-terrorism related offence and prosecuted, all were convicted of a non-terrorism related offence

2.1 Arrests by legislation

In the year ending 30 September 2024, there were 245 arrests for terrorist-related activity in Great Britain, 32 of which were under Section 41 of Terrorism Act 2000 (13%). The remaining 213 arrests (87%) were made under other legislation which includes arrests under non-terrorism legislation, such as the Police and Criminal Evidence Act (PACE) 1984.

3. Average line represents the median number (53) of quarterly arrests over the last 9 quarters.

2.2 Pre-charge detention under Section 41 of the Terrorism Act 2000

Once a suspect has been arrested by the police, they may be detained for a specified period of time before being charged, giving the police time to investigate and gather evidence related to potential terrorism offences. The current maximum period of detention under section 41 of TACT 2000 is 14 days (which was reduced from the previous limit of 28 days on 25 January 2011). This compares with a maximum of 4 days under standard arrest powers. Further details of the legislation can be found in the user guide.

There were 32 detentions under section 41 of TACT 2000 in the year ending 30 September 2024, up from 23 detentions in the year ending 30 September 2023. In the latest quarter, July to September 2024, there were 16 detentions. This is the highest number seen over the last 9 quarters, with the next highest being 9 in both July to September 2022 and January to March 2024. Of the 32 detentions in the year ending 30 September 2024, 27 led to a charge (84%).

Further details on the length and outcomes of detentions under section 41 of TACT 2000 can be found in annual data table A.02.

2.3 Other powers under Schedule 8 to TACT 2000

From the year ending September 2021 publication onwards, data has been collected and published on the number of persons detained and applications for extension of detention in Great Britain under Schedule 8 of the Terrorism Act 2000. Data has also been collected and published on the number of requests for access to a solicitor by persons detained in Great Britain under Schedule 8 of the Terrorism Act 2000. The user guide provides further details on these new statistics.

These statistics are classed as official statistics in development to acknowledge the relative early stages of development of this dataset. More information about official statistics in development can be found on the UK Statistics Authority website. Home Office statisticians aim to improve the quality of the data in future releases by working with data providers to improve quality assurance procedures.

Under Section 41 of TACT 2000, police officers have the power to arrest persons suspected of terrorism-related offences without a warrant. These arrest powers also allow the extended detention of persons beyond the maximum 4 days available under standard arrest powers, to a maximum of 14 days. Multiple applications for warrants of further detention may be made for one individual.

In the year ending 30 September 2024^{[footnote 3]}, of the 32 individuals arrested under section 41 of TACT 2000 in Great Britain, there were 29^{[footnote 4]} warrants of further detention under Schedule 8 of TACT 2000, which may include multiple warrants for the same individual.

Under Section 41 of TACT 2000, a person detained in police custody under the terrorism provisions is entitled to consult a solicitor privately. A police officer of at least the rank of superintendent can authorise a delay in permitting a detained person to consult a solicitor if they believe that exercising this right will result in any of the consequences listed in Schedule 8 of the act. Please see the user guide for further information. In the year ending 30 September 2024, of the 32 individuals arrested under section 41 of TACT 2000 in Great Britain, there was one instance where a request for access to a solicitor was delayed.

2.4 Charges

In line with the general convention for Home Office criminal justice statistics, when a person is charged or prosecuted for multiple offences at the same time, only the most serious offence is counted – usually the one that carries the highest penalty. This ‘principal offence rule’ means the statistics provide a count of individuals charged rather than the total number of charges. More detailed information on the principal offence rule can be found in the accompanying user guide. Further details of the legislation under which persons have been charged following an arrest for a terrorism-related activity can be found in annual data tables A.05a to A.05c.

At the time of data provision^{[footnote 5]}, of the 245 arrests for terrorist-related activity in the year ending 30 September 2024, 88 (36%) resulted in a charge, of which 70 were for terrorism-related offences.

Given the number of cases still to be finalised in the year ending 30 September 2024, the current charge rate may change over time. Until all cases in a given period are finalised, care should be taken when comparing charge rates over time.

Source: CTPHQ Coordination (see annual data table A.03)

Notes:

1. ‘Alternative action’ includes for instance, cautions for non-TACT 2000 offences, detentions under the Mental Health Act 1983, recall to prison.
2. ‘Bailed to Return’ includes those released on bail pending further investigation, and those who have absconded from bail. Those who were released under investigation (RUI) were previously unable to be recorded separately and were recorded as ‘released without charge’.

Charge rates have remained consistent since the year to 30 September 2018 (47%, 153 out of 324 arrests) with a mean rate of 44% between year to 30 September 2018 and year to 30 September 2023. In the most recent reporting period, year to 30 September 2024, the charge rate is 36% (88 out of 245 arrests). However, as cases progress over time, figures published in this release are likely to be revised. The effect on the arrests total will be minimal but the number of charges and convictions currently reported will likely increase in future releases, especially for cases from the more recent quarters where a greater number have not yet reached the point of charge or conviction.

Notes:

1. ‘Alternative action’ includes cautions for non-TACT offences, detentions under the Mental Health Act, recall to prison, and transfers to immigration authorities.
2. ‘Bailed to Return’ includes those released on bail pending further investigations, and those who have absconded from bail. Those who were released under investigation were previously unable to be recorded separately and were recorded as ‘released without charge’.

2.5 Prosecutions

As with charges, statistics on prosecutions are based on the principal offence rule, (see Section 2.3). Where an individual is prosecuted for more than one offence at a time, they are classified in terms of a single offence – usually the most serious.

Figure 2.6 shows the outcomes following a charge for a terrorism-related offence.

Further details of the specific legislation under which persons have been convicted following a charge for a terrorism-related offence can be found in annual data tables A.08a to A.08c.

7. Excludes convictions that were later quashed on appeal.
8. Includes other cases/outcomes such as cautions, transfers to UK Border Agencies, the offender being circulated as wanted and extraditions.

2.6 Demographics of persons arrested for terrorism-related activities

This section provides more detail on the demographic and other characteristics of persons arrested. It includes data on:

• sex
• age
• ethnic appearance
• nationality

Sex

As in previous years, and similar to other types of crime, the vast majority of those arrested for terrorism-related activity were males (202, 82%). Of the 245 arrests where the sex was known, there were 43 females (18%), an increase of 31 compared to the year ending 30 September 2023 (12, 7%). In comparison, there were 202 males (82%), an increase of 40 compared to the year ending 30 September 2023 (162, 93% of persons arrested).

Age

As in previous years, those aged 30 and above accounted for the most arrests (127, 52%). The number of arrests increased in all age groups except 17 and under, which decreased from 34 to 32 arrests, compared to the year ending 30 September 2023. Those aged between 18 to 20, 21 to 24, and 25 to 29 saw increases of 7, 6 and 7 respectively, but each decreased by one percentage point in proportion. Those aged 30 and over went from 74 to 127 compared to the previous year (43% to 52% of persons arrested).

Arrests for those aged 17 and under decreased from 34 individuals to 32. The proportion of those arrested aged 17 and under decreased by 6 percentage points to 13% compared to the previous year.

Ethnic appearance as recorded by the arresting officer

Figures in this section are based on the ethnic appearance of the person being arrested as recorded by the arresting officer.

Since June 2022, the data on those arrested for terrorism-related offences by ethnic appearance use the ONS 18+1 ethnicity codes^{[footnote 6]}, in line with the Census 2011 categories.

Following an internal review of these statistics during the March 2024 publication, Home Office analysts have amended the aggregation process, such that individuals with a self-defined ethnicity code of ‘A9 – Any Other Asian Background’ are now grouped under the ‘Asian’ category. Previously, these individuals were included under the ‘Other’ category. This change in reporting affects data for 3 years, the year to September 2021 to the year to September 2023 in table A.11a of the published annual statistical data tables and has a minimal impact on these groups. The data tables have been corrected to reflect this change.

In cases where ethnicity is known, arrests for those of White ethnic appearance accounted for 48% of arrests (114 out of 238). Arrests for those of Asian ethnic appearance accounted for 30% of arrests (72 out of 238)^{[footnote 7]}.

Figure 2.7: Proportion of persons arrested for terrorist-related activity by ethnic appearance^1,2, 30 September 2024

Source: CTPHQ Coordination Centre (see annual data table A.11b)

Notes:

1. As recorded by the police at time of arrest.
2. Excludes those whose ethnicity is not known (for instance, ‘Not stated’).

Nationality

Of those arrested in the year ending 30 September 2024, 67% considered themselves to be of British or British dual nationality, down 7 percentage points compared to the year ending 30 September 2023.

Overall, the proportion of those arrested who consider themselves British or British dual nationality has increased over the last 13 years. The proportion increased from 33% in the year ending September 2002 to 82% in the year ending September 2021 and has not fallen below 66% over the last 13 years. Overall, since 11 September 2001 (when the data collection began), 63% of those arrested considered themselves to be of British or British dual nationality.

3. Court proceedings

Main results

• in the year ending 30 September 2024, 86 persons were tried for terrorism-related offences, 33 more than in the year ending 30 September 2023
• of the 86 persons tried for terrorism-related offences, 85 were convicted (99%)
• of the 85 persons convicted of terrorism-related offences, 44 (52%) pleaded guilty and 41 (48%) entered a not-guilty plea

This section presents statistics on prosecutions for terrorism-related offences in England and Wales. It provides data on the number of persons prosecuted and convicted, including information on the legislation under which they were prosecuted. It also provides information on the length and type of sentence that each convicted person received. Data in this section is based on the trial completion date and is not directly comparable to the prosecutions data in Section 2, ‘Arrests and outcomes’, which is based on the date of arrest.

Data is provided to the Home Office by the CPS CTD. The data covers terrorism-related court cases that were completed in the 15 years from the year ending September 2010, up to the year ending September 2024.

The breakdown of data for terrorism-related offences by sentence lengths for defendants tried and convicted by the Crown Prosecution Service is excluded within this release as this data is currently not available to the Home Office.

3.1 Court proceedings

In the year ending 30 September 2024, 86 persons were tried for terrorism-related offences, 33 more than in the year ending 30 September 2023. This also represents a 5% decrease, with 5 fewer persons tried for terrorism-related offences from the peak of 91 trials seen in the comparable year ending 30 September 2018 (annual data table A C.01). Conviction rates remained consistent in recent years, with 89% (81 out of 91) of trials leading to a conviction in the year ending 30 September 2018, and 91% (48 out of 53) of trials in the year ending 30 September 2023, with conviction rates broadly similar in the intervening years.

The latest year had the highest conviction rate recorded since September 2010, with 99% (85 out of 86) of trials in the year ending 30 September 2024 leading to a conviction. The peak, for years ending September, in court proceedings in the year ending September 2018 followed on from the highest volume of terrorism-related arrests in the year ending September 2017.

Of the 86 persons tried for terrorism-related offences in the year ending 30 September 2024, 85 were convicted. Figure 3.1 shows the outcomes for the 86 persons proceeded against.

Notes:

1. Based on the principal offence for which the defendant was prosecuted against.
2. TACT offences include offences specifically under terrorism legislation.
3. Non-TACT offences include offences under other legislation.
4. Can include trials ending in a hung jury, or where the prosecution offered no evidence.

Of the 85 persons convicted of terrorism-related offences, 44 (52%) pleaded guilty and 41 (48%) entered a not-guilty plea. This was a similar proportion compared with the year ending 30 September 2023, where 26 of the 48 persons convicted (54%) entered a guilty plea. Data on this can be found in Table C.03 within the quarterly and annual data tables.

Data in this release is presented on the principal offence basis. This means that, when a person is tried for multiple offences in the same trial, the most serious offence with the largest sentence is shown in the data tables.

In the year ending 30 September 2024, the principal offences with the most convictions are Sections 11 to 13 of TACT 2000 (membership of a proscribed organisation) and Section 2 of TACT 2006 (dissemination of terrorist publications), both with 13 convictions. The next highest legislation in the latest year is Section 5 of TACT 2006 (preparation for terrorist acts) with 10 convictions.

4. Terrorist prisoners

Main results

• as at 30 September 2024, there were 254 persons in custody for terrorism and terrorism-connected offences in Great Britain, the highest number since comparable records began (30 September 2020)
• of those in custody, the majority (62%) were categorised as holding Islamist-extremist views; a further 30% were categorised as holding Extreme Right-Wing ideologies and 8% were categorised as holding Other ideologies
• of the latest data available (year ending 30 June 2024) a total of 58 prisoners held for terrorism and terrorism-connected offences were released from custody in Great Britain

Statistics presented in this section give information on the number of persons in custody for terrorism and terrorism-connected offences in Great Britain, including the jurisdictions of England and Wales, and Scotland. This includes both those that had been convicted and those being held on remand (that is, held in custody until a later date when a trial or sentencing hearing will take place). This section includes breakdowns of their ideology, self-defined ethnicity, self-defined nationality and self-defined religion.

Prior to June 2018, the Home Office published figures on both terrorist prisoners and domestic extremist/separatist prisoners. However, following feedback from data providers at HMPPS and SPS, it was decided that prisoners categorised as ‘domestic extremist/separatist’ prisoners would be counted within the ‘TACT/TACT-related’ cohort, where the threshold for this is met, such as for offences which the court has determined have a terrorist connection. This was to remove the previous subjectivity around the categorisation of domestic extremist prisoners.

From September 2020 onwards, the Ministry of Justice and Home Office formally adopted the definition ‘terrorism-connected offender’. ‘Terrorist connection’ is a statutory sentencing aggravating factor which permits courts to impose a terrorism connection ‘label’ to offenders who committed certain non-terrorist offences that had a terrorist connection. The terrorism connection label was introduced by the Counter Terrorism Act 2008 (CTA), and so is applicable for all relevant cases that ended after the date of its commencement (18 June 2009). Users should also note that this term applies to the statistics captured within the statistical publication for terrorism-connected offenders in custody with a terrorist connection. This definition replaced the previously used definition ‘terrorism-related offender’ which will no longer be used for the purposes of publishing official statistics for terrorist prisoners. The change in definition between the publication of statistics as at 30 June 2020 and 30 September 2020 caused approximately 10% of prisoners to be removed from the classification at that point. For this reason, figures for September 2020 onwards are not directly comparable with previous years or quarters.

‘Terrorism-related offender’ previously referred to prisoners who had been convicted or charged for offences which the court had determined to have a terrorism or extremism connection. This also included prisoners who may have been linked to, or co-defendants of, prisoners who were charged with a terrorist offence but they themselves were charged with another criminal offence. Users should also note that previous data concerning ‘errorism-related ffenders’, does not include prisoners listed in the ‘domestic extremist or separatist’ group as they did not meet the threshold for TACT or TACT-related offences (for example, those in custody for violent disorder).

This change in definition is in alignment with Part 2 of Schedule 19ZA of the Criminal Justice Act 2003 (as inserted by the Terrorist Offenders (Restriction of Early Release) Act 2020), which concerns those offenders who have not committed terrorist offences (that is, those listed in Part 1 of the Schedule) but who have committed other specified offences which the court has determined have a ‘terrorist connection’. That determination may only be made by the sentencing court in accordance with Part 3 of the Counter-Terrorism Act 2008 and only after consideration of the requirements specified in that Act. If the court determines that the offence has a terrorist connection it must treat that fact as a statutory aggravating factor and state in open court that the offence was so aggravated.

From June 2024 onwards, the Home Office published figures for the first time on the number of persons in custody for terrorism and terrorism-connected offences in the jurisdictions of England and Wales, and Scotland within Great Britain by terrorist prisoners’ ideology and self-defined ethnicity, following feedback from partners within the counter terrorism community to provide a more transparent breakdown.

Data on terrorist prisoners was provided to the Home Office by HMPPS and the SPS, giving information about the prison population for the 12 years from 30 September 2013 to 30 September 2024, and also at the end of the 9 quarters to 30 September 2024. Data on the number of prisoners released covers the 9 quarters to 30 June 2024. Prisoner release figures up to 30 September 2024 are not yet available as these will form a subset of the prison releases statistics which will be published by the Ministry of Justice in their Offender management statistics quarterly release in January 2024.

4.1 Persons in custody

As at 30 September 2024, there were 254 persons in custody for terrorism and terrorism-connected offences in Great Britain. This compares to 246 persons in custody as at 30 September 2023.

Of those in custody, 158 (62%) were categorised as holding Islamist-extremist views, 3 fewer compared to the year ending 30 September 2023. A further 76 (30%) were categorised as holding Extreme Right-Wing ideologies, 11 more than the year ending 30 September 2023. The remaining 20 prisoners (8%) were categorised as holding beliefs related to Other ideologies, the same compared to the year ending 30 September 2023.

Source: HMPPS and SPS (see annual data table P.01)

Notes:

1. The ‘Other’ category includes any prisoners holding ideologies including Dissident Irish Extremist, Domestic Extremist, Left Wing Extremist, no specific ideology, and not known.
2. Following changes agreed with the prison service, for figures at 30 September 2020 onwards, we have adopted the definition ‘terrorism-connected offender’ to replace the previously used definition ‘terrorism-related offender’ for this time-series.

As at 30 September 2024, the majority of persons in custody for terrorism and terrorism-connected offences in Great Britain have the United Kingdom as their self-declared nationality (207 out of 254, 81%). The next highest self-declared nationalities include Iraq, Bangladesh and Iran where 8 (3%) persons declared themselves Iraqi, 4 (2%) Bangladeshi, and 4 (2%) Iranian.

Of the 254 persons in custody for terrorism and terrorism-connected offences in Great Britain with a self-declared religion, 161 were Muslim (63%), 47 (19%) were Christian and 8 (3%) declared themselves as having no religion.

4.2 Persons released from custody

A total of 58 terrorist prisoners were released from custody in Great Britain in the year ending 30 June 2024 for which figures were available^{[footnote 8]}. This figure includes 12 offenders released between July 2023 and September 2023. There were slightly fewer releases between October 2023 to December 2023 compared to January 2024 to March 2024, rising from 15 to 16. There were 15 releases in the latest quarter, April 2024 to June 2024.

Of the 58 terrorist prisoners released from custody, 55 (95%) were persons released from custody after serving sentences, many of whom will be subject to meeting certain licence conditions.

Of the 58 released from custody, 21 had received sentences of less than 4 years, and 33 had sentences of 4 years or more. No one was released following an indeterminate sentence for public protection. One person was released who was serving a life sentence, whilst 3 persons had been convicted but not yet been sentenced.

5. Other police powers under the Terrorism Act 2000

Main results

In the year ending 30 September 2024:

• 92 persons were stopped and searched by the MPS under section 43 of TACT 2000; this was a decrease of 56% compared with a total of 210 in the year ending 30 September 2023, and the lowest number since data collection began
• there were 14 arrests resulting from a section 43 stop and search in the latest year, 5 fewer than the year ending 30 September 2023
• 2,527 persons were subject to the use of Schedule 7 to TACT 2000 in Great Britain; this was an increase of 2% compared with the year ending 30 September 2023 (where there were 2,469 examinations)
• 57% of examinations made under Schedule 7 of TACT 2000 in the United Kingdom resulted in at least one biometric identifier being taken from an individual (1,516 persons out of 2,637 examinations)

This section presents statistics on the use of stop and search powers available to the police under the Terrorism Act 2000 (TACT 2000). It includes data on the number of stop and searches, and resultant arrests, carried out under section 43 of TACT 2000 (by the MPS only) and section 47A of TACT 2000 (by all police forces). It also contains data on the use of powers under Schedule 7 to TACT 2000 in Great Britain. This includes the number of examinations, resultant detentions, strip-searches, the number of times postponement of questioning (usually to enable an individual to consult a solicitor) was refused, and the number of sea and air freight examinations. It also contains data on the number of persons where one or more biometric identifier was taken during an examination or a detention made under Schedule 7 of TACT 2000. For the purposes of this statistical publication, a biometric identifier (taken during an examination under Schedule 7) includes photographs, fingerprints and DNA samples.

Data on Schedule 7 is provided to the Home Office by the Counter Terrorism Policing Headquarters (CTPHQ). This section includes annual breakdowns for the last 13 years up to the year ending September 2024.

Data on section 47a stop and search is provided to the Home Office by police forces, and data on section 43 stop and search is currently provided on a quarterly basis for this release by MPS only. Data on section 43 stop and search is available for all police forces in the annual ‘Police powers and procedures’ stop and search report.

For data on section 43 stop and search numbers, users should note that there may be some variation in the figures reported for the same financial year and quarter between this statistical release and those in the Police powers and procedures England and Wales statistics due to the live nature of the data, where we expect small differences for different dates of data extraction and any updates made to records after each publication.

The statistics in this release on the number of stops and searches carried out by the MPS and persons arrested as a result of these, between 1 April 2023 and 30 September 2024, were provided to the Home Office by the MPS on 16 October 2024.

The statistics reported within the Police powers and procedures England and Wales bulletin, cover the period between 1 April 2023 and 31 March 2024 based on data provided to the Home Office by the MPS on 31 May 2024.

As part of quality assurance processes in Autumn 2024, Home Office analysts and the MPS found larger than expected differences between the statistics reported for the year ending March 2022 for the Police powers and procedures England and Wales statistics and the figures published in these statistics, which are summarised in Table 5.1. This was a result of missing data for the period between April 2021 and 1 May 2021, in quarter one of the year ending March 2022 in the data provided to the Home Office by the MPS. Please note that the data within Table 5.1 does not include ‘vehicle only’ searches. The MPS has provided this data and Home Office analysts have updated this in this release, which will supersede previously reported figures.

Moreover, users should also note that Home Office analysts and the MPS also identified that a small number of searches had been incorrectly recorded under section 47a legislation in the Police powers and procedures England and Wales statistics for the year ending March 2023. As agreed with the MPS, these searches were reclassified as section 43 with some of them under a different search type following subsequent revisions to the historical data which are available in this release and supersede those reported in the Police powers and procedures England and Wales statistics.

Home Office analysts and the MPS will continue to work together to ensure that the statistics are better aligned in future releases.

Following the Parsons Green attack, on 15 September 2017, the police used the power of stop and search under section 47a of TACT 2000 (previously section 44) for the first time. This power allows the police to exercise stop and searches when there is reasonable suspicion an act of terrorism will take place, and only when such powers are considered necessary to prevent such an act taking place. This was the first time they had been used in Great Britain since the legislation was formally amended in 2011. Following the attack on Parsons Green, 4 forces authorised the use of these powers: British Transport Police, City of London Police, North Yorkshire Police and West Yorkshire Police. There was a total of 128 stops (126 of which were conducted by BTP) resulting in 4 arrests (all BTP). There have since been no stop and searches under section 47a of TACT 2000.

Further details on the use of section 47a can be found in the code of practice for the exercise of stop and search powers.

5.1 Stop and search under Section 43 of the Terrorism Act 2000

Section 43 of TACT 2000 allows a constable to stop and search a person whom he/she reasonably suspects to be involved in terrorist activity. This section includes data from MPS only and excludes ‘vehicle only’ stops and searches.

In the year ending 30 September 2024, 92 persons were stopped and searched by MPS under section 43 of TACT 2000, the lowest number since data collection began and a decrease of 56% when compared with the 210 in the year ending 30 September 2023. There was a large reduction in the use of section 43 stops between the year ending 30 September 2011 (when the data collection began) and the year ending 30 September 2014, during which time numbers fell 70% (down from 1,210 to 360 stops). There was then an increase over the next 3 years, up to a total of 735 stops in the year ending 30 September 2017.

Since June 2024, the data on stops and searches of persons made by the Metropolitan Police under section 43 of the Terrorism Act 2000 by self-defined ethnicity are published using the ONS 18+1 self-defined ethnicity codes^{[footnote 9]}.

In the year ending 30 September 2024, there were 14 arrests resulting from a section 43 stop and search (down by 5), and a 26% decrease from a total of 19 in the year ending 30 September 2023.

Figure 5.1: Stop and searches under section 43 of TACT 2000, year ending September 2011 to year ending September 2024, MPS

Source: MPS (see annual data table S.01)

Notes:

1. Excludes ‘vehicle only’ searches.

In the year ending 30 September 2024, 15% of stops (14 arrests out of 92 stops) resulted in arrests, 6 percentage points higher than the year ending 30 September 2023. This is the highest arrest rate since comparable records began (year ending 30 September 2011), however the search and arrest numbers are much lower than previous years, with the year ending 30 September having the next highest arrest rate (383 searches and 42 arrests, 11%).

Notes:

1. Excludes ‘vehicle only’ searches.

Details on the overall use of stop and search in England and Wales can be found in the Home Office ‘Police powers and procedures, England and Wales’ annual statistical release. MPS also publishes monthly reports on the use of stop and search within its force area.

Ethnicity was stated in only 62% of stops (57 of 92) in the year ending 30 September 2024, the same proportion as the year ending 30 September 2023. The number of cases where ethnicity was known was at its highest at 92% in the year ending September 2012 and has declined since. This information relies on the person stopped being willing to define their ethnicity and the officer recording it accurately.

In cases where the ethnicity^{[footnote 10]} was known:

• 39% identified as ‘Asian or Asian British’
• 35% identified as ‘White’
• 19% identified as ‘Arab or other’
• 5% identified as ‘Black or Black British’
• 2% identified as ‘Mixed’

5.2 Schedule 7 to TACT 2000

Under Schedule 7 to TACT 2000, an examining officer has a number of powers, the uses of which are covered in this section. These include:

• examinations of persons and resultant detentions
• strip-searches
• refusals to postpone questioning (usually to enable an individual to consult a solicitor)
• examinations of goods

Data has also been provided on how frequently other powers have been used in Great Britain under Schedule 7 to restrict or qualify a person’s access to a solicitor. As well as ‘refusal to postpone questioning’, which has been published since 2016, this release now also covers use of powers where a person is:

• required to consult a solicitor by phone
• delayed access to a solicitor
• required to consult in sight and hearing of a qualified officer

From the year ending June 2019 publication onwards, data on the number of examinations made under Schedule 7 of TACT 2000 in the United Kingdom and the number of intra-UK examinations has also been collected. An intra-UK examination is when a person has been examined at a UK port either before or after a journey between one UK port and another UK port. This includes journeys between or within England, Wales, Northern Ireland and Scotland.

Moreover, as of the June 2021 publication of this release, data on the number of persons where one or more biometric identifier was taken during an examination made under Schedule 7 of TACT 2000 in the United Kingdom has also been provided. For the purposes of this statistical publication, a biometric identifier (taken during an examination under Schedule 7) includes photographs, fingerprints, and DNA samples.

Examinations and resultant detentions

An examining officer may stop and question individuals entering and leaving the country through ports, airports, international rail stations and the border area. When necessary they may also detain and search individuals. The aim is to determine whether or not that person is or has been concerned with the commission, preparation or instigation of acts of terrorism.

In the year ending 30 September 2024, a total of 2,527 persons were subject to the use of this power in Great Britain. This was an increase of 2% compared with the year ending 30 September 2023 (where there were 2,469 examinations), and a 96% decrease since the data was first collected in the year ending 30 September 2012 (when 61,711 persons were examined under Schedule 7). From 1 October 2011 to 30 September 2024, there has been a mean 21% decrease in examinations each year.

Figure 5.3 below shows the number of Schedule 7 to TACT 2000 examinations and result detentions in Great Britain for the 5 years to 30 September 2024.

Figure 5.3: Number of Schedule 7 to TACT 2000 examinations¹ and resultant detentions, year ending September 2020 to September 2024, Great Britain

Source: CTPHQ (see quarterly data table S.04a)

Notes:

1. Excludes examinations of unaccompanied freight.

There was a large reduction in examinations under Schedule 7 of TACT 2000 between 2019 and 2021 due to the impact of the COVID-19 pandemic on international travel. Passenger numbers at air and sea ports in particular were at unprecedented low levels. There has also been increased public scrutiny of this power in recent years, which may have driven a more targeted approach in its use. This is reflected in the increased rate of detention, with 63% of examinations in Great Britain in the year ending 30 September 2024 resulting in a detention (see Figure 5.3).

Since June 2022, data on examinations and resultant detentions made under Schedule 7 of the Terrorism Act 2000 by self-defined ethnicity are published using the self-defined ethnicity codes based upon the ONS 16+1 self-defined ethnicity codes with the addition of the ‘O2-Arab’ category^{[footnote 11]}, which comes under the ‘Other’ group.

Ethnicity was stated in 95% of cases. In cases where the ethnicity^{[footnote 12]} was known:

• 36% identified as ‘Chinese or Other’
• 30% identified as ‘Asian or Asian British’
• 22% identified as ‘White’
• 8% identified as ‘Black or Black British’
• 5% identified as ‘Mixed’

Figure 5.4 below shows the number of Schedule 7 to TACT 2000 examinations and result detentions in Great Britain for the 9 quarters to 30 September 2024.

Notes:

1. Excludes examinations of unaccompanied freight.

In the year ending 30 September 2024, 2,637 examinations were made under Schedule 7 of TACT 2000 in the United Kingdom, a slight decrease compared to the year ending 30 September 2023 when 2,642 examinations were made. Of the 2,637 examinations made in the year ending 30 September 2024, 374 (14%) were intra-UK examinations, compared to 392 of 2,642 (15%) in the year ending 30 September 2023.

In the year ending 30 September 2024, 57% of examinations made under Schedule 7 of TACT 2000 resulted in at least one biometric identifier being taken from an individual (1,516 persons out of 2,637 examinations).

5.3 Other powers under Schedule 7 to TACT 2000

The following section includes information on several additional powers under Schedule 7 to TACT 2000. This includes:

• strip-searches
• postponement of questioning refusals
• examinations of goods (sea and air freight)

Data on these powers has been collected by the Home Office since April 2015.

In the year ending 30 September 2024:

• 3 strip-searches were carried out under the power
• a total of 469 air freight examinations were carried out (a decrease of 44% compared with the year ending 30 September 2023); the volume of air freight examinations remains below pre-COVID-19 levels
• 150 sea freight examinations (an increase of 105% compared with the year ending 30 September 2023) were conducted in Great Britain which remains below pre-COVID-19 levels
• there were no occasions where postponement of questioning (usually to enable an individual to consult a solicitor) was refused

Furthermore, data has been provided on how frequently powers have been used to restrict or qualify a person’s access to a solicitor by: requiring the person to consult a solicitor by phone, delaying access to a solicitor, and requiring the person to consult in sight and hearing of a qualified officer. This data has been collected since April 2019.

In the year ending 30 September 2024, there were 5 instances where an individual was delayed access to a solicitor^{[footnote 13]}.

Details on each power can be found in the user guide.
