Five police officers are under investigation for manslaughter after the death of a 24-year-old man in police custody earlier this month.
Brian Ringrose, from Milton Keynes, was placed in an induced coma and died in hospital days after he was arrested by Thames Valley police on 27 January.
The Independent Office for Police Conduct said it was investigating the use of a “flexible lift and carry system” (Flacs) used to transport Ringrose to a police van when he was restrained using handcuffs and limb restraints.
The Guardian has requested more information from the National Police Chiefs Council on what Flacs is and how it is used.

A police officer has been found guilty of battery after he struck a child who was in custody in the face.
Thames Valley Police sergeant Matthew Myers hit the 16-year-old boy and made him strip naked, the Independent Office for Police Conduct said.
The watchdog said he abused his position as a custody sergeant last year in Banbury, Oxfordshire.
The 49-year-old was sentenced to a community order and 200 hours unpaid work at Luton Magistrates Court.
During the incident on 4 January 2020 the boy, who was in care and did not speak English as a first language, was left naked until a detention officer came into the cell to assist him.
