A WATCHDOG is appealing for witnesses in relation to the death of a man following police contact at a service station on Deeside.

Paul Wilson, 55, died at the Northop Services on the A55 eastbound carriageway on Tuesday, February 12 at about 8am.

After being arrested in Flint, Mr Wilson became unwell in an unmarked police vehicle en route to a police station.

Officers decided to take him directly to hospital but stopped at Northop Services to administer first aid when his condition deteriorated.

He was de-arrested. An ambulance was called and CPR continued until he died at the scene at about 8am.

The Independent Office for Police Conduct (IOPC) is now appealing for witnesses to come forward.

An IOPC spokesman said: "Investigators have begun gathering evidence and would like to trace a member of the public who assisted police officers with first aid.

"An inquest was opened by HM Coroner on Monday.

"A post mortem examination found Mr Wilson’s provisional cause of death to be pulmonary embolism due to femoral artery thrombosis and morbid obesity."
