Police are investigating after a suspected stowaway plunged to his death from a plane and landed in a busy London high street on Thursday morning.
The victim, who has not been identified, fell on to the roof of a business in Kew Road, Richmond, south-west London.
Police and an ambulance were called just after 9.30am and found the man dead at the scene.
A second man was found unconscious at Heathrow around an hour earlier.
He was taken to a west London hospital where police said he remains in a serious condition.
The two men are believed to have clung on to a British Airways plane as it flew more than 8,000 miles (12,875km) from Johannesburg in South Africa to Heathrow.
A Scotland Yard spokeswoman said: “A post-mortem examination will be held in due course and inquiries are ongoing to establish the male’s identity. No arrests have been made.”
