  1. The reasons for detention at Brook House broadly fell into three categories:
  • foreign nationals who had served a sentence in a UK prison, having been convicted of a criminal offence, and were due to be deported as a result (known as time served foreign national offenders or TSFNOs);1
  • individuals whose applications for asylum had been rejected and others thought to have entered or remained in the UK illegally; and
  • those whose applications for asylum were still being considered.


  1. The average proportion of detained people at Brook House who were TSFNOs during the relevant period was 33–35 per cent (see CJS000905; CJS000908; CJS000914; CJS000910; CJS000619; IMB000021; IMB000050; IMB000011; IMB000047; IMB000019). See also CJS0073709_060 para 6.1[]
