Question to the Home Office:

To ask the Secretary of State for the Home Department, what proportion of detainees who have escaped from detention or from escort in each of the last four years have been returned to detention.

The proportion of detainees who have escaped from detention or from escort in each of the last four years who have been returned to detention is 37% (7) of 19 detainees. One detainee was not returned to detention but located overseas. Major changes to the estate since 2010 have included the closure of the lower security site at Oakington Reception Centre in November 2010 and increased capacity at the higher security centre at Harmondsworth in July 2010. The management information above has been reached by the examination of individual records. It does not form part of published statistics and is not subject to the detailed checks that apply for National Statistics publications. It is provisional and subject to change.
