Police investigating an attack on a Watford football fan say a man has identified himself in a CCTV image released by detectives.

Nic Cruwys suffered "critical" head injuries in the assault after he had watched his team play Wolverhampton Wanderers at Molineux on 7 March.

Police said they received a call from a 20-year-old man after releasing an image on Monday.

Eleven people have already been arrested and bailed over the assault.

Mr Cruwys, 44, came under attack while making his way to the train station with a group of friends.

He has been left with potentially life changing injuries, police said.

Officers said they would speak to the man on Tuesday.
