Ten men were arrested after football-related disorder broke out in Chorley.
Before Saturday’s match between Bolton Wanderers and Blackburn Rovers, police launched an operation in anticipation of hundreds of football supporters meeting at Chorley railway station.
Just after noon, a member of the public reported 25 men squaring up to each other on Devonshire Road Rec and a fight broke out.
Police chased the men on foot down Devonshire Road, Fleet Street and Market Street.
Officers detained 10 men and they were all arrested on suspicion of conspiracy to commit violent disorder.
Police said the men, aged 15 to 22, all gave addresses in east Lancashire and are believed to support Blackburn Rovers.
Det Insp Paddy O’Neill, from Preston CID, said: “As a result of the operation put in place by our uniformed colleagues, serious disorder was averted on this occasion.
“However, we still haven’t got a full picture of what actually happened near the tennis courts on Devonshire Road Rec and we are appealing for anyone who witnessed the incident to contact Preston CID.
“I want to be clear, those involved in the co-ordination and preparation of pre-planned football-related disorder commit offences and need to be put in front of the courts to be dealt with - regardless of whether the disorder actually occurred or not.”
The men have all been released on bail.
