Since September 2008, information on the release details of individuals convicted of terrorism or terrorism-related offences has been held centrally. Since then, 11 terrorist offenders have been released to approved premises. Data about offenders released into approved premises (formerly known as bail/probation hostels) are collected centrally, from information supplied by individual approved premises. The data collected do not include offence details more generally. Obtaining this information dating back to 2007 would have to be done on a case by case basis, and as such could be collected only at disproportionate cost.
Probation areas may apply to register with the National Offender Management Service as Critical Public Protection Cases (CPPCs) those offenders, including offenders convicted of terrorism or terrorism-related offences, who present the highest levels of risk of harm. Where offenders are registered as CPPCs, areas may apply for additional funding to strengthen local risk management plans: Such funding can cover temporary additional staffing in approved premises, a member of staff to escort offenders outside the approved premises, improvements to security equipment at approved premises or other specific interventions which contribute to public protection.
