Police officers who restrained a hospital patient who later died were not responsible for his death, the Independent Police Complaints Commission has concluded.
The IPCC inquiry into the death of Anthony Stewart also cleared the officers involved of any misconduct.
Mr Stewart, who lived in Walsall, died in July 2003 after he was restrained by a number of police officers at Walsall Manor Hospital while staff sedated him.
He was then admitted to the Dorothy Pattison psychiatric hospital, under section two of the Mental Health Act.
But, shortly after his arrival, Mr Stewart experienced breathing difficulties and was transferred back to the Manor Hospital, where he died.
John Crawley, the IPCC's Commissioner for the West Midlands, said: "A thorough investigation into Mr Stewart's death has been carried out by West Midlands Police and after consultation with the CPS I am satisfied that the actions of the police officers did not cause the death of Mr Stewart. I am also satisfied that there was no misconduct on the part of the officers.
"I have met Mr Stewart's family to explain the nature and extent of the investigation and the findings in respect of officers."
The CPS is still considering whether any charges should be brought in respect of the care Mr Stewart received in hospital.
