A man has died after he was hit by a Tube train at Old Street as he tried to save his brother who had fallen on to the tracks.

The 35-year-old from London was trying to pull his 32-year-old brother, from Manchester, to safety when they were both struck.

The “tragic accident” left the younger brother with serious injuries, said British Transport Police.

They are appealing for witnesses to the incident, which happened at 12.20am on Sunday.

A spokesman said on Monday: “The men were treated at the scene by colleagues from the London Ambulance Service and then taken to Royal London Hospital in a critical condition.

“The man from London died in hospital later that day. The 32-year-old from Manchester remains in a stable but critical condition.

“Officers are not treating the incident as suspicious and are now working to put together a fuller picture of what happened.”

Det Sgt Adrian Naylor said: “I am keen to speak to anyone who can help us understand how the two men came to be struck by a train.”
