There are no relevant figures for prisoners, but they are published for offenders who have been diverted to hospital. The bulletin, ‘Statistics of Mentally Disordered Offenders’, covering England and Wales, summarises information about mentally disordered offenders detained as ‘restricted patients’ in psychiatric hospitals; it also provides information on their re-offending rates. The last bulletin is for 2006:
This shows that, for the combined figures of those released in 1999-2004 and then followed up for two years, 2 per cent. re-offended through violent or sexual offences; and 7 per cent. through any offence. These figures only relate to those first released on a conditional discharge, and exclude those recalled.
