A man had his teeth loosened after being punched in the face and pushed into a train carriage at King’s Cross station.

The 42-year-old victim was assaulted at around 12.20am on Saturday, December 12.

Detective Constable Dean Percival said: “The victim was seeing a friend on to a King’s Cross to Cambridge train on platform six when he was attacked.

“He was punched in the face and pushed into the train carriage sustaining cuts and bruises to his face.

“The attack loosened two of his front teeth, and it is feared he may have sustained permanent nerve damage.”

After reviewing CCTV, officers believe the attacker left the train on platform six prior to its departure.

Police believe he was intending to travel to Hertfordshire and may have links to Hitchin, Letchworth or Stevenage.

DC Percival added: “I would like to reassure the public that violent incidents like this are rare on the rail network. I would also like to appeal for anyone with information to get in touch.

“I think the person in the image has information which could prove useful to our investigation. Who is he?”
