The coroner had described aspects of Mr Patterson's treatment as "dreadful' but said he believed there was no direct link with his death. Leonard Gorodkin told Manchester coroner's court: "I do not believe that in this case the possibility of neglect should be added to your verdict." But the jury rejected his advice to return a verdict of "misadventure to which neglect contributed".
Mr Patterson, 31, from north London, had absconded from a seven-year prison sentence while on home leave four years ago. He was then arrested in Stockport, Greater Manchester, on suspicion of stealing and held at Stockport police station due to a prison officers' dispute.
On the day of his death, he was taken to Stockport magistrates' court where he spent eight hours lying naked and handcuffed on a stone floor before being transferred to a holding cell at nearby Denton police station where he was later found dead.
There was medical disagreement on the cause of death, but it was considered to have been a "complex metabolic disorder" resulting from drug withdrawal symptoms and gastroenteritis. Mr Patterson was a heroin addict.
A jury at an earlier inquest said that Mr Patterson was unlawfully killed. But the police overturned the verdict in the High Court, which ordered a new hearing.
Deborah Coles, of the pressure group Inquest which has funded the Patterson family's legal representation, said the decision was a damning indictment of his treatment. "The attitude of the police and police doctors was one of callous indifference and appalling neglect." But a Greater Manchester police spokesman said: "We acted at all times in accordance with the medical advice."Reuse content
