Prior to the June 2019 publication, those who were released under investigation were unable to be recorded separately and were recorded as 'released without charge'. From June 2019 the Home Office has published numbers on those bailed to return & released under investigation as one figure.

Data presented here are based on the latest position with each case as at the date of data provision from CTPHQ Coordination Centre (23 October 2023). Therefore individuals released under investigation may have their outcome updated over time, and the numbers change accordingly. More information regarding individuals arrested and charged for terrorist-related activity can be found in the Home Office’s Operation of police powers under the Terrorism Act 2000 statistics release.
