Detectives have released images of a man whose body fell from the under carriage of a plane heading for Heathrow.
The man's body was discovered in Mortlake, London, on the morning of Sunday 9 September and he was pronounced dead at the scene.
A post-mortem gave the cause of death as multiple injuries.
Police hope the man can be identified from an e-fit and an image of the distinctive tattoo on his left arm.
It is possible the man is from Angola, as he was found with Angolan currency in his possession and police enquiries confirmed that a flight from Luanda, Angola, was overhead shortly before the body was discovered.
He is believed to be an African man aged between 20 and 30 years old. He is 5 feet 4 inches tall and of slight build.
