An investigation has been launched following the death of a man who was taken into custody.
Ian Dyche was arrested on suspicion of criminal damage on April 29 after Staffordshire Police was called to flats in Cannock where he lived.
The 35-year-old was found to be unresponsive during a medical check in his cell at Cannock Police Station at 7.45am the following morning.
An ambulance took him to New Cross Hospital in Wolverhampton where he passed away on May 8.
The Independent Office for Police Conduct is gathering evidence including CCTV footage from the custody block and body worn video from the arresting officers.
Further tests to establish the cause of death have been made as a post mortem was inconclusive.
A coroner opened and adjourned an inquest on May 16.
IOPC Commissioner Derrick Campbell said: “Our sympathies are with Mr Dyche’s family and everyone else affected by his death. Our inquiries are at an early stage and we will be carrying out a thorough investigation of all the circumstances.”
