The report by the Independent Investigations Office said the unidentified man was picked up by police following reports he was causing a disturbance in a park on West 7th Avenue on Oct. 7 at around 7 p.m. PT.
At the time, police said the man was drunk but couldn't be taken to a nearby detox centre because he was barred from the facility. The man accepted a ride home instead and was placed without handcuffs in a police van.
But when the van arrived at the man's home seven minutes later he was unconscious and efforts to resuscitate him failed, according to the IIO.
He was pronounced dead upon arrival at Vancouver General Hospital.
"Following a thorough investigation by IIO investigators, chief civilian director Richard Rosenthal concluded that there was no evidence that any police officer committed an offence in relation to this death," said a statement issued by the IIO on Tuesday morning.
The man's name has not been publicly released.Suggest a correction
