PFD Monitor interpretation
Lack of guidance and training on safe use of force for resistant prisoners with items in their mouths
Wider context from the report
“Following the investigation by the Prisons and Probation Ombudsman a recommendation was made that you should ensure that there is clear guidance and training on the safe use of force when resistant prisoners have items in their mouth which might compromise their breathing. In evidence at the inquest I heard that suitable training on this topic did not appear to have been delivered and that it would be appreciated by prison staff. I wonder therefore if the national training you provide could include control and restraint for prisoners with items in their mouths. ”

PFD Monitor interpretation
Insufficient emphasis on heightened risks of prone restraint when multiple breathing-affecting factors are present
Wider context from the report
“Importance of heightened risk of prone restraint when multiple factors affecting breathing are present 1. The current and earlier training plans, manuals and policies examined as part of the evidence in this inquest make clear references to risks associated with: (a) positional asphyxia; (b) handcuffs and limb restraints; (c) incapacitant spray; (d) acute behavioural disorder or symptoms thereof; (e) lack of oxygen due to physical exertion; (f) drug/alcohol intoxication; and (g) seizures. Although there is some cross-referencing between the various risk factors, the heightened risk to a person in prone restraint when a number of these factors are present is not emphasised or sufficiently emphasised. The multifactorial matters that can impact on a person’s ability to breathe and the heightened risks to a person in a position of prone restraint when experiencing such multiple factors are critical to the assessment of risk. ”

Verbatim wording from the response
“Monitoring is covered across a number of Lessons such as ABD, Epilepsy, conscious and unconscious casualty and Positional Asphyxia.

Mr Hywel Llewelyn Hughes · Prevention of Future Deaths report

This summary was generated using AI from the published report. Please read the original report for the complete account.

Report summary

Mr Hywel Llewelyn Hughes was forcibly removed from a nightclub, restrained face down by door staff, and later declared deceased in hospital on 3 May 2003. The inquest concluded that the medical cause of death was traumatic asphyxia and that police actions were inappropriate and more probably than not contributed more than minimally to his death. Concerns included training and monitoring of detainees during restraint and transport, and shortcomings in the licensing, training, auditing and review of door supervisors.
