A £5,000 reward has been offered to help catch the killer of a man whose body was found at a house in Harrogate three months ago.
Mr McLeod was last seen alive at Harrogate Hospital
Robert McLeod, 49, was last seen on 12 January when he received hospital treatment. His body was found at a house in Robert Street nine days later.
Mr McLeod suffered numerous injuries and it is thought he was assaulted in the days leading up to his death.
The reward has been put up by the Crimestoppers Trust.
Detective Chief Inspector Noel Roberts, who is leading the investigation, said: "Despite the fact that this investigation has been ongoing for the past three months, the circumstances surrounding the death remain unclear and we continue to treat it as suspicious.
"However it is clear that Mr Pride-McLeod had been injured in some way and we suspect he had been the victim of an assault at some time leading up to his death.
"I am confident that someone, somewhere will have information relating to this death and the surrounding circumstances. I hope that the reward will be sufficient incentive to persuade them to come forward."
Mr McLeod often walked with a zimmer frame and weighed just five stone (31.75kg), despite being 5ft 7in tall.
