POLICE say they are treating the death of a man at a house in Soundwell as “unexplained”.
Detectives are waiting for the results of “further forensic medical analysis” after an initial post-mortem examination could not give a conclusive cause of death.
The man, who was in his 40s, was found when officers were called to a house in Hayward Road, shortly after 5.40pm on July 25.
A police spokesperson said: “They found a man who was unresponsive and sadly, despite the efforts of officers and ambulance crew, he died at the scene.
“A man, known to the deceased, was arrested from the address. He has been released under investigation as the cause of death is yet to be confirmed.”
Police had initially said they were treating the death as “suspicious” but said the results of a forensic post-mortem examination had “proved inconclusive”.
A spokesperson said: “Pending the results of further forensic medical analysis, officers are treating the death as unexplained.”
The Avon & Somerset force has referred itself to the Independent Office for Police Conduct in relation to the incident, as there had been “prior police contact” with those involved.
Neighbourhood Chief Inspector Keith Smith said: “Our thoughts are with the man’s family in their loss.
“We’ll continue our thorough investigation into what has happened and will prepare a report for the coroner, should no criminal offences be identified.”
He called on anyone with information which could help the investigation to call 101 and quote the incident reference number 5224 194 416.
