Cold case investigators are trying to solve the mystery of a body found in a children’s playground 55 years ago. 

The man was found dead in the playground on Secker Street, near Waterloo Station, on July 18, 1970. 

Police believed he may have fallen from a nearby roof, but despite clues being left behind he remains unidentified to this day. 

Locate International, a charity dedicated to locating and identifying missing or unnamed people, is appealing for help in solving the mystery.

“This might be the last chance to do so, however – had he lived, he would be possibly close to 80-years-old. 

“Those who knew him may be around the same age, so we ask you to take a close look and speak to anyone you know who may be able to help. 

“It only takes one person to contact us with one clue for his identity to be found.”

The man is believed to have been no older than his mid-20s, white, around 5ft7ins tall with short fair hair, blue eyes and a gap between his front teeth. 

Clues found on him include a train ticket to Farnborough. 

Police investigations at the time looked at whether the man was station with the military there but investigations proved fruitless. 

Other theories are that he may have travelled into the city to see a free Pink Floyd concert at Hyde Park.
