Inquiry Progress Update

The Inquiry continues to work towards public hearings commencing in November 2021 and will provide more information on the schedule for those hearings in due course.

 Core Participants

The Chair has now designated a total of 18 individuals and organisations as Core Participants in the Inquiry. Most recently designating “DS” and “NAO”, who were individuals detained at Brook House in the relevant period, as Core Participants. The Chair’s determinations can be found on the Inquiry’s website, along with an updated list of all the Inquiry’s Core Participants.

Witness statements

The Inquiry has requested witness statements from a number of individuals who were detained at Brook House and from G4S staff (including Detention Custody Officers and Managers, and Healthcare staff who worked for G4S Health Services).  We have also requested statements from the Home Office, Her Majesty’s Inspectorate of Prisons, The Prisons and Probation Ombudsman, G4S and G4S Health Services.


The Chair has now instructed an additional expert, Mr Jonathan Collier, to assist her in respect of the ‘Use of Force’ at Brook House.  Mr Collier will be assisting the Inquiry by considering the training of staff members in Control and Restraint/Use of Force techniques during the relevant period. Mr Collier’s opinion will be sought on individual instances of Use of Force for which we have video footage or other evidence. He will also be asked to comment on the recording and follow-up of Use of Force incidents.
