The man's body was found by builders in the rear garden of an address in Cowdrey Road.

Police have now released a craniofacial reconstructive image in the hope someone may know who he is.

A post-mortem indicated a traumatic head injury and radiocarbon dating indicated the body was buried in the early 1960s.

A biological profile from an anthropologist indicated the deceased was likely of Asian ancestry and ages between 35 and 55.

Police say there is a strong possibility that he'd had some form of medical procedure to the head.

They also say the man has been wearing a shirt, red silk tie, trousers, shoes and socks indicative to the 60s era.

Detective Chief Inspector Kate Kieran who leads the investigation, said: “We want to hear from anybody who has any information, or any suspicions about who this person might be. Perhaps family have spoken about somebody who went missing about this time. Perhaps the image or description reminds you of someone, or a person that other family members have spoken about.  This is a sixty-year-old mystery and your information could help us solve it. If you can help then please make contact and tell us what you know.”
