DETECTIVES baffled by the identity of the man found dead near an Oxford park and ride are now investigating if he was a foreigner.

Officers were yesterday no closer to learning the man's name four days after he was discovered on wasteland near the Seacourt park and ride off Botley Road. Checks on people missing locally and nationally, tip-offs from the public, investigations with other police forces and fingerprint, dental and DNA records have yet to yield a positive match.

Police, who issued an efit, right, on Thursday, are checking with immigration officials to see if they can discover if he was a recent arrival in Britain.

The man was white, slim and around 5ft 11ins, and was in his early to mid-20s.

His body was discovered at 9.10am on Tuesday, but it emerged last night the man might have been at the spot since Sunday night.

Detectives have been investigating whether the man killed himself in an elaborate suicide involving a length of drainpipe, a knife and rope. A post mortem examination determined he died from a head wound.

No identification was found with the man's body. Police spokesman Victoria Bartlett said: "Unfortunately, we are still no further forward."
