New appeal over mystery man found in Hereford
Police trying to trace the identity of a man found four months ago want to trace another man he was with on the day he was discovered.
A vulnerable man, who told police he was called Roger, was found in Hereford bus station car park on 7 November.
West Mercia Police said he has "no memory of who he is".
The force wants to trace a man, described as being in his 40s, who walked with "Roger" to Hereford County Hospital.
Police said a member of the public came across the two men between 16:20 and 16:30 GMT on 7 November in the car park in Commercial Road.
They then helped walk "Roger", along with the unknown man, to the hospital but as they approached KFC on Stonebow Road, a passing ambulance was flagged down.
The man with "Roger" was described as white, in his 40s, of a slim build and about 5ft 8ins tall with dark wavy hair and glasses.
He appeared to be wearing a jacket with long sleeves, combat style trousers and black boots, police said.
"This man may have vital information that can help us piece together where Roger had been prior to him being found," the force said.
"Roger" was currently in the care of Herefordshire Council and inquiries were ongoing to establish if he had been reported missing by family or friends nationally or internationally, police said.
The force said there had been "numerous new lines of enquiry" following its previous public appeals but they still do not know who he is.
He had said his name was Roger Curry but, after further inquiries, police now believe Roger Curry may have been a now-deceased friend.
