This is the face of a man whose naked body was found on Piccadilly line train tracks.

British Transport Police (BTP) have released an e-fit and appealed for information following the gruesome discovery between Osterley and Boston Manor stations in the early hours of last Tuesday.

Detectives have been working to try and identify the man, who appeared to have been hit by a train before tube workers found him at 2.34am.

Detective Inspector Ian Baker said: “We’ve made extensive enquiries to establish his identity but unfortunately we have so far been unable to do so.

"It's rare that we release an e-fit image of someone in these circumstances but it's very important that we identify him and contact his family to let them know what has happened.

"Our forensic artist created an e-fit of him and we are releasing it in the hope that someone may recognise him, even if they don't know him well, and come forward to us with information that could help us identify him.

“The fact that he was found naked is very unusual and it’s vital that we work out who this man is and piece together his movements before his death.”

The man was black, between 5ft 7ins and 5ft 9ins tall and has a large build with a shaved head. He is thought to be between 25 and 35 years old.

DI Baker added: “We would also like to speak to anyone who may have seen a man matching this description in the area around Osterley station from about 1am on Tuesday morning.”

Anyone with any information should call British Transport Police on 0800 40 50 40, quoting incident 42 of 6/7/10.
