A man's corpse found under a railway bridge in Hounslow last month is one of 233 unidentified bodies on the books of the Metropolitan Police.
The body of a white European man, believed to be aged 20-30, was discovered under the stairs of the bridge on July 8.
He joins a long list of people who have never been identified after their bodies were found at sites across the capital between 1966 and the present day.
Drug and drink overdoses, suicide and heart attacks were the most common known causes of death given by the Met in its response to a Freedom of Information request by Trinity Mirror's data unit.
But some of the circumstances listed were more unusual, like that of the man found in a canal-side footpath near mitre Bridge, close to Wormwood Scrubs, in 1972, his head having been blown off in a nitroglycerine explosion.
Another body, that of an Afro Caribbean man believed to be aged 25, was discovered in the landing gear of an inbound flight from Jeddah, Saudi Arabia, in 2002.
Several of the bodies had been lying undiscovered for months or even years, like that of a 30 to 35-year-old man whose decomposed remains were found in a gravel pit in Chertsey Road, Feltham, in 1994 - up to three years after he was believed to have died.
A woman in her 60s whose body was found under asbestos sheeting at the rear of a property in Brent in 1983 was believed to have been dead for two to 10 years.
