The incident took place in front of a number of passengers and now police are hoping that the video will encourage witnesses to come forward with information.

PC Alex Trivino said: “The train assault took place on board as it pulled into Milton Keynes at 12.20am on Saturday, 15 November.

“The victim was travelling in a first class carriage. Throughout the journey, a man and a woman were talking to various other passengers in the carriage.

"As the train pulled into Milton Keynes, this man assaulted the victim, causing a cut underneath his left eye which required treatment at A&E.

"I am confident that someone will recognise this man from these good quality moving images.

"I want to urgently speak to him about what happened. I would also like to hear from anyone else who was on the train, and saw what happened, and has not yet come forward to police."
