A plane stowaway may have fallen to his death in Britain, according to reports.

Police are investigating after a body was found on the roof of a west London building near Heathrow Airport.

It’s believed that the unidentified man plunged to his death after stowing away on a British Airways flight from South Africa.

A second stowaway was found unconscious in the undercarriage of the plane. He survived the flight, but is in serious condition.

Scotland Yard spokeswoman said the death of the first man is currently being treated as unexplained, but that officials will conduct a postmortem examination.
