Five people were arrested when trouble broke out between rival football fans at a match between Chorley and Chester.
Lancashire Police said trouble flared outside Victory Park before kick-off on Saturday, and again after the match when about 100 fans invaded the pitch.
More than 3,000 fans attended the Evo-Stik league first division game, in which top of the table Chester beat second-placed Chorley 1-0.
Those arrested have been charged with public order offences.
The match drew Chorley's biggest crowd since the 1970s. There were 3,223 spectators at the ground, which usually sees about 250-300 at a home game. Kick-off was delayed for 15 minutes because of congestion.
Chorley's chairman Ken Wright said the trouble had spoiled what should have been a great day for the club.
"I'm obviously very disappointed that the game should be targeted by a hooligan element from both sets of supporters," he said.
"Fortunately the police responded promptly and there was no actual fighting, it was just taunting basically, and the police would appear to have the matter in hand.
"We are encouraging families to come to the football club and really the last thing that we want is for the club to be tarred with the fact that we have a hooligan element, because certainly we don't, we've not experienced this in the past."
