POLICE believe they may now know what killed a man found dead at a train station in Southampton.

The body of a man believed to be in his late 20s was discovered on a pathway behind Millbrook station on Sunday.

Officers are ruling out the possibility he was attacked after last night's post mortem revealed his body showed no signs of physical injury.

But police are awaiting reports of a toxicology test to determine whether he took any drugs in his final moments.

His body was discovered at 11.30am on Sunday but it is believed he may have died on Saturday afternoon.

He is yet to be formally identified but documents found in his pockets suggest he was 29 and Polish.

Officers are liaising with police in Poland to trace his next of kin.

Detective Inspector Damon Kennard from Shirley CID who is working on the case said: “Formal identification is still being awaited but we strongly believe he is of eastern European descent and enquiries are going on in Poland.

“The early indications are that it's more likely to be a drug related death but we need to await confirmation of a toxicology result.”

The pathway, which runs parallel to the railway line from the outskirts of the city centre all the way to the station is regularly used by commuters and trainspotters.

He urged anyone who used the pathway since Saturday afternoon to contact police and added:  “We encourage anyone who saw a male in his late 20s walking around there to call us.”

Anyone with any information should contact DS Boughay at Shirley CID on 101.
