Detectives are appealing for public help in their hunt for a suspect after an unprovoked attack on a train in east London left a student with a damaged jaw.

British Transport Police have today released CCTV images of the man they want to question about the incident at Hackney Wick station on Sunday, September 9.

A 20-year-old Indian student was on a train travelling towards Stratford at 8.30pm when he was approached by a man on the train as it pulled into Hackney Wick.

“The man suddenly punched him in the face,” said Det Sgt Alan Bardsley. “The student was left with damage to his jaw and needed hospital treatment.

“This was a violent, unprovoked attack on an innocent young man who was simply minding his own business.”

The attacker got off at Hackney Wick and ran along the railway track, causing a delay to trains.

Police have since obtained CCTV images of the man they want to speak to and believe he may have been travelling from either Tottenham or Walthamstow towards Hackney Wick.

Detectives are appealing for anyone who recognises him to contact Transport police on 0800-405040, or anonymously to Crimestoppers on 0800-555111, quoting reference reference B8/LNA of 04/10/12.
