A man who may have been leaning out of a train door window has died from a head injury. Police and ambulance crews responded to the incident at Wandsworth Common station in south west London on Sunday (7 August).
The incident took place on a Gatwick Express train, which had departed from the airport to London Victoria station. Authorities have sine refuted initial claims that the man had been decapitated.
"We are aware of a number of reports on social media which say the man was decapitated as a result of this incident. However, this is not the case," the BBC quoted Inspector James Tyrrell as saying.
A spokesman for the British Transport Police said: "Emergency services rushed to the scene but despite their best efforts, nothing could be done to save him.
"Our investigation remains at an early stage, but initial enquiries suggest the man may have been leaning out of a train door window when he suffered a blow to the head."
"The incident is being treated as non-suspicious and a file will be prepared for the coroner," he added. The man is believed to be in his 20s and authorities are working on identifying him so that his next of kin can be informed.
A London Ambulance spokesman said: "We were called at 5.34pm [BST] to reports of an incident at Wandsworth Common Railway Station. We sent an ambulance crew, a single responder in a car and an incident response officer to the scene, alongside London's Air Ambulance.
"We treated a patient at the scene for a head injury. But sadly, despite the efforts of the crews, the patient was pronounced dead by the doctor from the air ambulance."
