London Underground is investigating procedures following the death of a medical student in a horrific accident.

Edwin Doubleday, son of sculptor John Doubleday, died after falling from an underground train at Liverpool Street station last weekend as he travelled home from Manchester University to visit his family in Great Totham.

A London Underground spokeswoman said the investigation will concentrate on procedures.

She said the train was being driven into sidings and the driver would have told passengers to leave the train three times.

"We can only speculate on what happened, but it may be this young man did not hear the message or saw the train was empty. He tried to get off on to a platform and fell to his death."

It is thought Mr Doubleday, 23, tried to get off the train by going through the emergency exit between the carriages to get on to the platform and fell on to the track.

His body was seen by a following train driver. He was only three months away from becoming a doctor.

A British Transport Police spokesman said the death was not being treated as suspicious and there had been witnesses to what happened.

A report would be made to the coroner.

Speaking today the headteacher who taught Edwin has spoken of the "numbness" felt by the school at his death.

Bob Reed, of the Anglo-European School at Ingatestone, said his tragic death had deeply shocked him and his staff.

"We are all totally shocked and stunned by the loss of somebody with so much potential. He was a very nice person, very popular and he had a wonderful sense of humour."

Edwin left the school after GCSEs to study A-levels at Fettes College, Edinburgh, where Tony Blair was once a pupil.

A funeral service was due to take place today (Friday).
