A number of men are wanted by police after fighting broke out between Preston North End and Blackburn Rovers fans at Ewood Park in March.
The men are believed to have been involved in post-match clashes with Rovers fans during the Lancashire Derby in Blackburn on March 9.
Police had been called at around 4.25pm following reports of fighting after the EFL Championship game at Ewood Park.
The group are alleged to have been involved in violent clashes with rival supporters in the Northgate area of Blackburn before they were dispersed by officers and escorted from the area.
One Rovers fan was punched in the face and had to be taken to Royal Blackburn Hospital to be treated for a head injury.
Seven men were later spoken to by police in connection with the disorder.
Following enquiries over the past four months, police say they now want to speak to three men (pictured), who are believed to be Preston North End fans.
PC Dan Fish, Lancashire Police’s Football Risk Management Officer, said: "We want to identify a number of men in connection with disorder following a football match in Blackburn.
