Answer for Arrests for Terrorism

Answered By: 
The Mayor

The data below shows the number of terrorism related arrests made by MPS officers over the last three years.  It is important to note that not all of these arrests took place in London as MPS officers may have made arrests in other regions. 

It is also important to note that the charge rate in more recent years is likely to be lower than previous years; this is because a number of cases in the arrests for the period ending August 2017 are incomplete, as the person may have been released on bail pending further investigation. Given that these cases will eventually lead to a charge, release, or alternative action, charge rates will change over time.

*Until all cases in a given period are complete, caution should be taken when comparing charge rates over time, as described above.

'TACT' includes arrests made under Section 41 of the Terrorism Act 2000 which gives the police the power to arrest a person whom they reasonably suspect to be a terrorist, without a warrant. This is similar to the powers of arrest contained in wider criminal legislation.

'Other legislation' includes arrests under non-terrorism legislation, such as the Police and Criminal Evidence Act 1984.
