A man who was arrested over an attack which left a rugby league supporter in a coma has been released on bail.
David Singer, 32, from Halifax, suffered serious head injuries when he was set upon outside Halliwell Jones Stadium in Warrington on 26 September.
He had seen Halifax play Featherstone Rovers in the Championship Grand Final.
A 26-year-old Pontefract man, arrested on Thursday on suspicion of assault and violent disorder, has been bailed pending further inquiries, police said.
He must report back to police on 1 December, Cheshire Police said.
Ambulance technician Mr Singer had travelled with his parents and friends to watch the game and was returning to his coach in the car park when he was attacked.
Police inquiries have suggested that fans wearing Featherstone colours were targeting Halifax fans as they moved back to the car park after the match.
Officers believe there may be other Halifax supporters who were subjected to abuse or violence before Mr Singer was attacked and have urged them to come forward.
