Investigators hope a computer-generated image of a man found dead in woodland more than 10 years ago will finally help them solve the mystery of who he is.
The man was found dead near Balmore Golf Club, in East Dunbartonshire, on 16 October 2011.
It is thought he could have been dead for up to six months before he was discovered.
But now, investigators at the Scottish Cold Case Unit at Glasgow Caledonian University have released a new facial reconstruction and 3D images of the man’s clothing in a fresh bid to solve the 11-year puzzle.
There were no suspicious circumstances surrounding the man’s death, who detectives have estimated as between 25 and 34 years old.
However, forensic analysis has revealed he suffered injuries before his death which may have affected his appearance, quality of life and gait.
Dr Maureen Taylor, co-director of the cold case unit, said: “We know he had a chip to one of his front teeth and injuries to his nose and jaw that he sustained in the months leading to his death.

“These injuries were not only left untreated, but would have caused him significant pain.
“We also believe that he may have walked with a limp or had difficulty walking.”
Investigators said the white European man was between 5ft 8in and 6ft 1in tall and of slight build, with light-coloured hair.
He was discovered wearing a blue Topman T-shirt with a maroon diagonal stripe on the front, a blue zipped cardigan bearing the logo Greek Pennsylvania, light-coloured jeans and black waterproof walking shoes, commonly bought in Lidl.
In a nearby Nike messenger-type bag, investigators found items including toiletries, clothes, headphones, chargers, a lighter and cigarette papers.
The images were produced by the University of Dundee and are being shown online alongside photos of the man’s belongings and drone footage of the woodland, close to Golf Course Road, where his body was found.
