Enforcement instructions This old Home Office/UK Border Agency manual contains guidance and information for officers dealing with enforcement immigration matters within the United Kingdom. Chapter 55 is entitled 'Detention and temporary release.' Paragraph 55.10 states: 'The following are normally considered suitable for detention in only very exceptional circumstances, whether in dedicated immigration detention accommodation or prisons: ... Those suffering from serious mental illness which cannot be satisfactorily managed within detention (in criminal casework cases, please contact the specialist mentally disordered offender team). In exceptional cases it may be necessary for detention at a removal centre or prison to continue while individuals are being or waiting to be assessed, or are awaiting transfer under the Mental Health Act.'
