1. Introduction

1.1 Time period covered and data sources

This release covers the use of police powers under terrorism and subsequent legislation in Great Britain on a quarterly basis up to the year ending 30 June 2022. It also covers arrests for terrorist-related activity under other legislation such as the Police and Criminal Evidence Act (PACE).

The statistics in this release draw on a range of 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
• gender, 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
• sentence length of those convicted for terrorism-related offences

The Terrorist prisoners section uses data from HM 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 Act 2000 (TACT)-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 Metropolitan Police Service (MPS) and CTPHQ, and includes statistics on the:

• number of stops and searches carried out by MPS under s.43 of TACT 2000
• number of stops and searches carried out by police under s.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 number of cordons under s.33 of TACT 2000

From the year ending June 2019 publication onwards, data have also been collected and published on the total number of examinations and detentions made in the United Kingdom as a whole under Schedule 7 to TACT 2000, as well as how many examinations related to intra-UK journeys. An intra-UK examination is when a person has been examined under Schedule 7 TACT 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.

Furthermore, data have 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. Including: required to consult a solicitor by phone, delayed access to a solicitor, and required to consult in sight and hearing of a qualified officer.

Moreover, from the year ending June 2021 publication onwards, data has also been collected and published on the number of persons where one or more biometric identifier was taken during an examination made under Schedule 7 of the Terrorism Act 2000 in the United Kingdom. For the purposes of this statistical publication, a biometric identifier (taken during an examination under Schedule 7) includes photographs, fingerprints and DNA samples.

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.

It is important to note that these new statistics are classed as ‘experimental’. Experimental statistics are new official statistics undergoing evaluation. More information about experimental statistics 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 CTPHQ to develop quality assurance procedures.

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, and detail about the legislation and categories referred to in this release.

A flow chart summarising the Arrests and outcomes section of this release can be found in Annex A.

2. Arrests and outcomes

Key results

• in the year ending 30 June 2022, there were 203 arrests for terrorist-related activity in Great Britain, 20 more than in the previous 12-month period (an increase of 11%)
• at the time of data provision^{[footnote 1]}, 49 arrests resulted in a charge (24%), of which 44 were for terrorism-related offences
• in the year ending 30 June 2022, of the 36 individuals arrested under s41 of TACT 2000 in Great Britain who were subsequently detained, there were 26 applications for extension of detention granted by a judicial authority under Schedule 8 of TACT 2000 (multiple applications may be made for one individual)
• in the year ending 30 June 2022, of the 36 individuals arrested under s41 of TACT 2000 in Great Britain who were subsequently detained, there were 35 requests for access to a solicitor, all of which were allowed immediately

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.

Prior to the June 2018 publication (covering the period to 31 March 2018), data in this release was restricted to arrests where the offence was considered to be related to terrorism. In response to feedback from stakeholders, Home Office statisticians widened the scope of the data collection to include all arrests with a terrorist element whether the offence was terrorism-related or not. This better reflects policing activity in recent years. Data in this release now contain information on all arrests related to terrorism activity, including a full back series.

Since the December 2019 publication (covering the period to 30 September 2019), postal charge requisitions and summonses have been included as part of the figures on arrests. This decision was taken following engagement with CTPHQ, as the postal charge requisitions and summonses can lead to terrorism-related charges and convictions. See the user guide for more detail.

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 are 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 have not 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 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 are provided to the Home Office by the CTPHQ Coordination Centre and are taken from a live database. This section includes annual breakdowns of the data from the 11 September 2001 (when the data collection began) to year ending June 2022, as well as quarterly trends over the most recent 9 quarters. The data were based on the latest position of each case as at the time of provision to the Home Office (on 15 July 2022).

A flow chart summarising this section is included in Annex A. This follows individuals from the point of arrest through to charge (or other outcome) and prosecution. Data tables A - A.01 to A - A.12c include data on arrests and outcomes. Annual tables, which breakdown the data by rolling years to June, are also provided alongside this release.

2.1 Arrests

In the year ending 30 June 2022, there were 203 arrests for terrorist-related activity in Great Britain, 20 more than the previous 12-month period (an increase of 11%) (Figure 2.1).

Figure 2.1: Arrests for terrorist-related activity, by legislation, years ending 30 June 2002 to 30 June 2022, Great Britain^1,2,3

Source: CTPHQ Coordination Centre (see data table A - A.01)
Notes:

1. Figures for the year ending 30 June 2002 include data from 11 September 2001 onwards.
2. ‘Other legislation’ includes arrests under non-terrorism legislation, such as the Police and Criminal Evidence Act 1984.
3. Includes arrests that are considered by the CTPHQ Coordination Centre to be terrorism-related, either at the time of arrest or at a subsequent point in the investigation.

There were reductions in the number of arrests starting from April to June 2020. The reductions were most evident in arrests under non-terrorism legislation and may reflect the general reduction in traditional crime during this period when there were public health restrictions in place to control the spread of the COVID-19 virus. This effect was most marked in April to June 2020 during the national lockdowns in England and Wales with just 31 arrests in this quarter. Following the easing of restrictions over the summer months, the number of arrests increased (for example, up to 55 arrests between October to December 2020). During the third national lockdown the number of arrests fell again, between January to March 2021, down to 39. In the latest two quarters, between January and March 2022 and April and June 2022, the number of arrests increased, to 50 and 49, respectively.

Notes:

1. ‘Other legislation’ includes arrests under non-terrorism legislation, such as the Police and Criminal Evidence Act 1984.
2. Includes arrests that are considered by the NCTPOC to be terrorism-related, either at the time of arrest or at a subsequent point in the investigation.

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 held 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 s.41 of TACT 2000 is 14 days (which reduced from the previous limit of 28 days on 25 January 2011). This compares with a maximum of four days under standard arrest powers. Further details of the legislation can be found in the user guide.

There were 37 detentions under s.41 of TACT 2000 in the year ending 30 June 2022, up from 32 detentions in the previous year. Of the 37 detentions in the latest year, 19 led to a charge (51%).

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

2.3 Other powers under Schedule 8 to TACT 2000

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. In the year ending 30 June 2022, of the 36 individuals arrested under s41 of TACT 2000 in Great Britain who were subsequently detained, there were 26^{[footnote 2]} applications for extension of detention granted by a judicial authority under Schedule 8 of TACT 2000.

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 June 2022, of the 36 individuals arrested under s41 of TACT 2000 in Great Britain who were subsequently detained, there were 35 requests for access to a solicitor, all of which were allowed immediately.

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 data tables A - A.05a-c.

At the time of data provision^{[footnote 3]}, of the 203 arrests for terrorist-related activity in the year ending 30 June 2022:

• 49 (24%) resulted in a charge, of which 44 were for terrorism-related offences
• 94 (46%) persons were released pending further investigation
• 50 people (25%) were released without charge
• 10 (5%) faced alternative action, for example receiving a caution or recalled to prison

Given the number of cases still to be finalised in the latest year, the current charge rate shown in the more recent years/quarters is likely to be lower than final figures which will be published in subsequent releases. Until all cases in a given period are finalised, care should be taken when comparing charge rates over time.

Notes:

1. ‘Alternative action’ includes cautions for non-TACT 2000 offences, detentions under the Mental Health Act, recall to prison etc.
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 were previously unable to be recorded separately and were recorded as ‘released without charge’.

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 also 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 2.5 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 data tables A - A.08a-c.

5. Terrorism-related charges and convictions include some charges and convictions under non-terrorism legislation, where the offence is considered to be terrorism-related.
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.
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

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 (95%). Five of the 203 arrests where sex was known were females (5%). This was a fall of seven arrests and five percentage points compared with previous 12-month period. The decrease in proportion of female arrests was driven by the increase in the number of males arrested in the latest year, which increased by 28.

Age

As in previous years, the ‘30 and over’ age-group accounted for most arrests (41%). The largest increase was in the 18-20 age group which increased from 17 to 30, while the under 18 and 21-24 age groups increased by 9 and 8, respectively.

Among those who were arrested, 16% were aged under 18 (up from 13% in the previous year). While this was the highest proportion seen in an annual period, it was largely a result of falls in arrests of those in older age-groups.

Ethnic appearance as recorded by the arresting officer

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

From the September 2022 publication onwards, data on those arrested for terrorism-related offences by self-defined ethnicity will be published using the ONS 18+1 self-defined ethnicity codes^{[footnote 4]}.

Arrests for those of White ethnic appearance accounted for 44% of arrests (89 out of 203). Arrests for those of Asian ethnic appearance accounted for 35% of arrests (72 out of 203)^{[footnote 5]}.

Figure 2.6: Proportion of persons arrested for terrorist-related activity by ethnic appearance^1,2, 30 June 2022

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

1. As recorded by the police at time of arrest.
2. Excludes those whose ethnicity is not known.

Nationality

Of those arrested in the latest year, 75% considered themselves to be of British or British dual nationality, down nine percentage points compared to the previous year. The proportion increased from 35% in the year ending June 2002 to 79% in the year ending June 2015 and has not fallen below 69% since. Overall, since 11 September 2001 (when the data collection began), 62% of those arrested considered themselves to be of British or British dual nationality (Table 2.1).

2. Only the first 10 countries, by number of persons arrested for terrorist-related activity, are included in the table.
3. Figures for Great Britain include those with ‘British dual’ nationality.

3. Court proceedings

Key results

• in the year ending 30 June 2022, 66 persons were tried for terrorism-related offences, eight more than in the previous year
• of the 66 persons tried for terrorism-related offences, 58 were convicted (88%)
• of the 58 persons convicted of terrorism-related offences, 40 (69%) pleaded guilty and 18 (31%) 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 are based on the trial completion date and are not directly comparable to the prosecutions data in section 2, Arrests and outcomes, which is based on the date of arrest.

Data are provided to the Home Office by the Crown Prosecution Service Counter Terrorism Division (CPS CTD). The data cover terrorism-related court cases that were completed in the 12 years from the year ending June 2010 up to the year ending June 2022.

3.1 Court proceedings

In the year ending 30 June 2022, 66 persons were tried for terrorism-related offences, eight more than in the previous year, but a fall of 34 (34%) from the peak of 100 trials in the year ending June 2018 (data table A C.01). This peak in court proceedings in the year ending June 2018 followed on from the highest volume of terrorism-related arrests in that year.

Of the 66 persons tried for terrorism-related offences, 58 were convicted. Figure 3.1 shows the outcomes for the 66 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.

3.2 Sentencing

The most common sentence length in the latest year was of less than four years, which accounted for 41% of sentences (24 of 58 convictions). Of these, 17 sentences were between one and four years (29% of total), and seven were less than a year (12% of total). There were also 15 sentence lengths between four and 10 years, accounting for 26% of sentences.

Those given a life sentence accounted for 3% of all those sentenced in the latest year (two sentences). There were 2 sentences of 10 years or more, an increase from zero in the pervious year. The number of non-custodial sentences increased from nine to 14 in the latest year, the highest in an annual period since data collection began, making up 24% of sentences handed down, up seven percentage points on the previous year.

Of the 58 persons convicted of terrorism-related offences, 40 (69%) pleaded guilty and 18 (31%) entered a not-guilty plea. This was a higher proportion compared with the previous year, when 34 of the 52 persons convicted (65%) entered a guilty plea.

Notes:

1. Based on the trial completion date.
2. The ‘Other’ category includes hospital orders and non-custodial sentence.

4. Terrorist prisoners

Key results

• as at 30 June 2022, there were 238 persons in custody for terrorism-connected offences in Great Britain
• of those in custody, the vast majority (66%) were categorised as holding Islamist-extremist views; a further 27% were categorised as holding Extreme Right-Wing ideologies and 7% were categorised as holding Other ideologies
• a total of 39 prisoners held for terrorism-related or terrorism-connected offences were released from custody in Great Britain in the latest year for which figures are available (year ending 31 March 2022)

Statistics presented in this section give information on the number of persons in custody for terrorism-connected offences in Great Britain. 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 ethnicity, nationality, ideology and 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 HM Prison and Probation Service (HMPPS), 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, i.e. 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 have formally adopted the definition ‘Terrorism-Connected Offender’. 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 roughly 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.

This definition change 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/matters specified in that Act.

Data were provided to the Home Office by HMPPS and the Scottish Prison Service (SPS), giving information about the prison population for the 11 years from 30 June 2013 to 30 June 2022, and also at the end of the nine quarters to 30 June 2022. Data on the number of prisoners released cover the nine quarters to 31 March 2022. Prisoner release figures up to 30 June 2022 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 July 2022.

4.1 Persons in Custody

As at 30 June 2022, there were 238 persons in custody for terrorism-connected offences in Great Britain.

Of those in custody, 157 (66%) were categorised as holding Islamist-extremist views, four more compared to the previous year. A further 64 (27%) were categorised as holding Extreme Right-Wing ideologies, up by 31% and a nine percentage point increase compared to the previous year. The remaining 17 prisoners (7%) were categorised as holding beliefs related to other ideologies, one percentage point lower compared to the previous year.

Source: CPS CTD (see data tables A P.01)
Notes:

1. The ‘Other’ category includes any prisoners not classified as holding a specific ideology.
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.

4.2 Persons released from custody

A total of 39 terrorist prisoners were released from custody in Great Britain in the latest year for which figures were available (year ending 31 March 2022)^{[footnote 6]}. This figure includes 27 terrorism-connected offenders released between April 2021 and September 2021 and 12 terrorism-connected offenders between October 2021 and March 2022.

Of these, 29 (74%) were persons released from custody after serving sentences, many of whom will be subject to meeting certain licence conditions.

Of the 39 released from custody, 11 had received sentences of less than four years, and 18 had sentences of four years or more (including one life sentence). No one was released following an indeterminate sentence for public protection. 10 people had been convicted but not yet been sentenced.

5. Other police powers under the Terrorism Act 2000

Key results

• in the year ending 30 June 2022, 396 persons were stopped and searched by the Metropolitan Police Service under s.43 of TACT 2000; this was a decrease of 12% compared with the previous year’s total of 452
• in the latest year, there were 30 arrests resulting from a s.43 stop and search, 17 less than the previous year (47)
• in the latest year, 2,662 persons were subject to the use of Schedule 7 to TACT 2000 in Great Britain; this was an increase of 5% compared with the previous year (where there were 2,525 examinations)
• in the year ending 30 June 2022, 46% of examinations made under Schedule 7 of TACT 2000 resulted in at least one biometric identifier being taken from an individual (1,311 persons out of 2,830 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 s.43 of TACT 2000 (by the Metropolitan Police Service (MPS) only) and s.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 s.47a stop and search are provided to the Home Office by police forces, and data on s.43 stop and search are currently provided on a quarterly basis for this release by MPS only. Following a change made to the Police Powers and Procedures statistical collection, this data is now available for all police force areas and will be published annually here on GOV.UK.. Data on Schedule 7 are provided to the Home Office by the Counter Terrorism Policing Headquarters (CTPHQ). This section includes annual breakdowns for the last 12 years up to the year ending June 2022.

Following the Parsons Green attack, on 15 September 2017, the police used the power of stop and search under s.47a of TACT 2000 (previously s.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, four 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 four arrests (all BTP). There have since been no stop and searches under s.47a of TACT 2000.

Further details on the use of s.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.

There was a large reduction in the use of s.43 stops between 2011 (when the data collection began) and 2015, during which time numbers fell 66% (down from 1,280 to 439 stops). There was then a general increase in the next four years, up to a total of 699 stops in 2019. In the year ending 30 June 2022, 396 persons were stopped and searched by MPS under s.43 of TACT 2000, the lowest number since data collection began and a decrease of 12% when compared with the 452 in the year ending 30 June 2021.

From the June 2022 publication onwards, data on stops and searches of persons made by the Metropolitan Police under s43 of the Terrorism Act 2000 by self-defined ethnicity will be published using the ONS 16+1 self-defined ethnicity codes^{[footnote 7]}.

In the latest year, there were 30 arrests resulting from a s.43 stop and search, down 17 and a 36% decrease from the previous year’s total of 47. 8% of stops resulted in arrests, two percentage points lower compared to the previous year.

Ethnicity was only stated in 66% of stops in the latest year, one percentage point lower compared to the previous year, the lowest proportion since data collection began in 2011. The number of cases where ethnicity was known was at its highest at 93% in the years ending June 2012 and June 2013 and has steadily 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 8]} was known:

• 37% identified as ‘White’
• 33% identified as ‘Asian or Asian British’
• 16% identified as ‘Black or Black British’
• 11% identified as ‘Chinese or Other’
• 4% 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 have 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

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.

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 June 2022, a total of 2,662 persons were subject to the use of this power in Great Britain. This was an increase of 5% compared with the previous year (where there were 2,525 examinations), and a 96% decrease since the data were first collected in the year ending 30 June 2012 (when 61,049 persons were examined under Schedule 7). Prior to the most recent year there had been average annual falls of 28%.

There was a large reduction in examinations under Schedule 7 of TACT 2000 between 2020 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. This is still impacting numbers of examinations now. 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 (see Figure 5.3).

From the June 2022 publication onwards, data on examinations and resultant detentions made under Schedule 7 of the Terrorism Act 2000 by self-defined ethnicity will be published using the ONS 16+1 self-defined ethnicity codes^{[footnote 9]}.

Ethnicity was stated in 80% of cases, the lowest proportion since data collection began in 2011. In cases where the ethnicity^{[footnote 10]} was known:

• 35% identified as ‘Asian or Asian British’
• 32% identified as ‘Chinese or Other’
• 20% identified as ‘White’
• 8% identified as ’Black or Black British’
• 5% identified as ’Mixed’

Notes:

1. Excludes examinations of unaccompanied freight.

In the year ending 30 June 2022, 2,830 examinations were made under Schedule 7 of TACT 2000 in the United Kingdom, 9% higher than the previous year when 2,607 examinations were made. Of the 2,830 examinations made in the year ending 30 June 2022, 554 (20%) were Intra-UK examinations, compared to 578 of 2,607 (22%) in the previous year.

In the year ending 30 June 2022, 46% of examinations made under Schedule 7 of TACT 2000 resulted in at least one biometric identifier being taken from an individual (1,311 persons out of 2,830 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 have been collected by the Home Office since April 2015.

In the year ending 30 June 2022:

• five strip-searches were carried out under the power
• a total of 465 air freight examinations (a fall of 43% compared with the previous year); the volume of air freight examinations still remains significantly below that of pre-Covid levels
• 209 sea freight examinations (a decrease of 87% compared with the previous year) were conducted in Great Britain
• there were no occasions where postponement of questioning (usually to enable an individual to consult a solicitor) was refused.

Furthermore, data have 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. These data have been collected since April 2019.

In the year ending 30 June 2022, there were five instances where an individual was delayed access to a solicitor.

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