The family of a man left in a coma after being viciously beaten in York, are being urged to come forward by detectives.
Stephen Eastwood, 45, has been unconscious in York District Hospital since being found with serious head injuries at the site of the old Reg Vardy garage on Lawrence Street on March 27.
Despite extensive police enquiries, detectives have been unable to trace any next of kin.
Officers believe he was attacked with a hammer.
Detective Inspector Ian Dyer, of York CID, said: “Stephen has been in a coma for over a week now since he was discovered unconscious and badly injured after the brutal attack. There has been no change in his condition and sadly there has been no family members to support him at his bedside.”
Mr Dyer added: “I am keen to trace any members of his family who could potentially help his recovery and offer him the support he needs to get over his ordeal.”
Four people have been arrested.
A 25-year-old woman has been released on conditional bail, while the others have been released without further police action.
Anyone with information should call 101.
