A man in his late 30s has been rushed to hospital with life threatening injuries after being hit by a train.

The man was struck by the train on platform One at Sutton Station just after 8.30am today. It is believed he slipped down the side of the train

The station closed for over two hours and hundreds of commuters had to find alternative routes during the morning rush.

The London Air Ambulance landed in the nearby B&Q car park and the fire brigade and police also attended.

Onlookers saw the man being brought out on a stretcher at 9.30am. He was taken to St George’s Hospital in Tooting with head and serious leg injuries.

He is said to be suffering from life changing and life threatening injuries.

A spokesperson for the British Transport Police said officers are working to establish the full circumstances surrounding the incident – which is currently being treated as non-suspicious.

Janine Holness arrived at Sutton station just as the incident happened and said: “As I was about to walk to the platform they asked everyone to leave platform One.

“I was across from the train and noticed the passengers looked distressed.

"I heard on the radio of the station workers ‘He's under the train, we need to make the announcement’.

“Then you heard ‘He's still alive he's conscious’.

“I'm under the impression from other commuters that he slipped down the side of the train.

“As I was walking home you can see onto the platform and you could see him on the platform.

“The paramedics and station staff were getting everyone off of the train.

"They had made them walk to the front of the train, obviously to prevent people from seeing what had happened. He appeared to be under the back of the first carriage.

“It's so sad my thoughts are with his love ones.”
