A man was killed after leaning his head out of a train bound for Victoria station in a horrific commuting accident which shook passengers.

Emergency services rushed to the scene but said "nothing could be done to save him".

He died instantly near Wandsworth Common at around 5.30pm on Sunday (August 7) from head injuries, although British Transport Police have said it is was 'not due to decapitation', despite reports suggesting it was.

A British Transport Spokesperson said: "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."

Inspector James Tyrrell from BTP said: “We are aware of a number of reports on social media which say the man was decapitated, however this is not the case.

“We are continuing to investigate the circumstances of the incident, which has been reported to the Rail Accident Investigation Branch (RAIB), and I’d urge anyone who saw what happened to contact us.”

According to reports the gruesome accident happened in front of a horrified mother and daughter, from Dorset, as the train sat in Wandsworth Common station in south London.

Pronounced dead at the scene

A spokeswoman for London Ambulance Service said: "We were called at 5.34pm to reports of an incident at Wandsworth Common railway station.

"We sent an ambulance crew, a single responder and a car and an incident response officer to the scene alongside an air ambulance.

"We treated a person at the scene for a head injury but sadly they were pronounced dead by the doctor from the air ambulance."

Officers are currently working to identify the man and inform the next of kin.
