POLICE have released pictures of a man they want to speak to following an attack on a 34-year-old man at Highgate Tube station.

The victim was assaulted on the escalator at the Northern Line station at 1.40pm on Thursday, April 9.

Officers are hoping to identify the man, pictured in the CCTV images, in connection with the incident which took place at 1.40pm.

Investigating officer PC Martin Wilson said: "A man and two women were escorting a party of very young children up the escalator at the same time as the victim.

"A verbal altercation took place between the victim and the man, before the victim was assaulted, leaving him with bruising and swelling to his face."

Following the incident the man and two women left the station and are believed to have boarded the number 134 bus towards Muswell Hill.

PC Wilson added: "This was a vicious attack and I would urge anyone with any information about this incident to come forward and talk to us.

"We are particularly keen to speak to the two women who were part of the group on the escalator."

Anyone with information about the incident, or who recognises the man in the CCTV images, is asked to contact British Transport Police on 0800 40 50 40 or call Crimestoppers anonymously on 0800 555 111
