DETECTIVES launched an investigation today after the body of a man was discovered in a flat in York.

Police said they were called to the address in High Petergate by the ambulance service at about 1.20am.

A North Yorkshire Police spokesman said: "The male resident of the house was found dead. The circumstances of his death are being investigated."

A post mortem examination, to establish how the man died, was due to be held in York this afternoon.

Police said they were unable to give any further details until the examination had been carried out.

People working in nearby businesses said they knew nothing of the incident.

Tim Foster, proprietor of Foster's Jewellers, said: "There was an officer there when I arrived at work this morning at about 9am. I had a word with him and he assured me everything was in order."

Mr Foster said that he was aware the building was used for residential purposes, but he knew nothing about who lived there.

A member of staff at the Ancient World shop said: "We have just opened and have no idea what has happened. We would not like to comment."
