To ask Her Majesty's Government how many people arrested for terrorist offences since 2001 had previously served custodial sentences. [HL1883]

The Home Office does not collect the information requested.

The Home Office, Ministry of Justice and Attorney-General's Office are currently working with the National Co-ordinator for Terrorist Investigations to improve the quality of data relating to those arrested, charged, convicted and imprisoned under terrorist legislation and under other legislation but considered terrorist-related. As soon as this is complete, a statistical bulletin covering this information will be published by the Home Office.

Although the bulletin will not cover statistics in relation to previously served custodial sentences, it will, for the first time, provide detailed statistics on terrorism arrests and convictions.

The bulletin is due to be published shortly.
