Naked death man tests prove inconclusive
Tests on a man who died after being arrested while naked in a County Durham field have proved inconclusive.
Kirk Williams was detained by police for behaving "erratically" in a field off the Moorhouse Estate, near Eaglescliffe, Teesside, on Sunday.
He was arrested by Cleveland Police and later taken to the James Cook University Hospital, where he died.
The Independent Police Complaints Commission (IPCC) is investigating his death.
Cleveland Police said further tests would be carried out to establish the cause of death.
IPCC investigators have met Mr Williams's family and begun house-to-house inquiries in the area where he was arrested.
An IPCC spokesman said Mr Williams's erratic behaviour continued in the police cells and a doctor advised that he should be taken to hospital.
An ambulance was called and it was noted that Mr Williams's vital signs were deteriorating, the spokesman added.
He was taken to hospital but he died a short time later.
IPCC Commissioner Nicholas Long said: "My sympathies go out to Mr Williams's family and friends.
"Our investigation will examine his arrest and detention thoroughly.
"The location of the arrest was near to houses and adjacent to a busy road, so I am sure people may have witnessed some aspects of the incident.
"Any piece of information, no matter how insignificant you believe it to be, could be key evidence for our investigation."
