CCTV images of four football fans suspected of being involved in a derby day disturbance have been released by police.

Officers investigating trouble at the end of the Burnley versus Blackburn Rovers game at Turf Moor in March want to speak to the four men in connection with the incident.

Supporters from both sides were in the David Fishwick Stand during the Premier League fixture, which Rovers won 1-0.

But immediately after the final whistle, a number of Burnley fans were forced back by police as they vented their frustrations at their bitter rivals.

Just a few rows across in the away section, Rovers fans ripped up 150 seats and smashed toilets in the concourse.

A number of people have been arrested in connection with the disorder, which is alleged to have occurred in the home section of the stand, also known as the Cricket Field Stand.

Football Intelligence Officer DC Shaun Juriansz said: "We are keen to speak to these men as they may have information to help with our inquiries and I appeal to anyone who recognises them to contact us.

"The vast majority of football fans are law abiding people who pose us no problems whatsoever.

“This disturbance, which involved a large number of people, happened at the end of the match.

"Fortunately no one was injured but we are keen to speak to these men and anyone else who has information to help with our investigation.

"We want people of all ages to be able to enjoy the football in safety and we will not tolerate anyone who might compromise that by behaving in a violent or anti-social manner.

“Anyone involved in violent or anti-social behaviour should be under no illusions as to the firm action that will be taken."

The East Lancashire derby attracted a huge police response with Blackburn fans bussed straight to the ground in the build up to the lunchtime kick off.

The arrangements were a mirror of the first fixture, held at Ewood Park last October.

But clashes inside and outside the ground saw more than 40 people arrested and an investigation launched into the actions of police who were accused of using heavy-handed tactics to keep Burnley fans at bay.

Video footage was posted on the internet and Lancashire Constabulary referred their controlling of the match to theIndependent Police Complaints Commission (IPCC).

However, IPCC investigators decided to allow the police’s Professional Standards Department to carry out the investigation instead.

The investigation is still ongoing.

There were also concerns raised that Rovers fans had been allowed to carry bottles of beer into the stand during the match amid suggestions of a crush in the concourse.
