Ten men arrested following a brawl between Brighton and Hove Albion and Crystal Palace football fans have been released on bail, police said.
Violence broke out in London between the two sets of supporters after the Championship clubs were involved in separate fixtures on November 10th.
A group of 10 men were questioned on suspicion of violent disorder this weekend and have been bailed until early January.
Four of the men were arrested in Sussex while six were held in Croydon and other parts of south London, Scotland Yard said.
Violence broke out in the King's Cross area after Brighton and Hove Albion drew 3-3 at Wolverhampton Wanderers and Crystal Palace secured a 2-1 victory at Peterborough United.
The arrests this weekend came as the rival clubs met each other in the league, at Palace's Selhurst Park, in south London.
