A stowaway who is believed to have clung on to a plane has fallen to his death, while another is in hospital.
The two men are believed to have been clinging to a British Airways flight from Johannesburg to Heathrow.
The victim was found on the roof of notonthehighstreet.com’s headquarters on Kew Road, Richmond, at about 09:35 BST on Thursday. Police said his death was being treated as unexplained.
The man who was injured is in a critical condition in hospital.
The Met Police said it could not confirm if the two cases were linked.
In a statement, the force said: “At this time there is no evidence to link the death to the discovery of a stowaway in the undercarriage of a plane at Heathrow Airport; however this is one line of enquiry into identifying the deceased and the circumstances of his death.”
