An investigation has been launched after a man died in police custody following the use of CS spray during his arrest.
The man was found to be unresponsive in the back of the police van by the time he arrived at the custody station following a journey of about four miles.
He was later pronounced dead in hospital and the Independent Office for Police Conduct (IOPC) is investigating.
Greater Manchester police said the man, in his 30s, had been arrested by officers following an alleged domestic disturbance in Oldham at about 11.35pm on Friday.
A police spokesman said officers “used CS spray to detain the man” during his arrest on suspicion of breach of the peace.
“During the arrest attempts, the officers deployed CS spray before putting him in the back of a van,” said Chief Supt Neil Evan.
“On arrival at Ashton police station, the man was found to be unresponsive and he was taken to hospital where he was sadly pronounced dead.
“We have since been providing his family with support from specially trained officers at this difficult time.
“We have made a mandatory referral to the IOPC, who are independently investigating and we will continue to cooperate with them fully.”
