Six teenagers have been arrested over football-related violence in Sunderland.
The group, aged between 15 and 17, were detained after the Black Cats' match against Luton Town on 18 March.
Northumbria Police said a number of people had been involved in violence outside The Wheatsheaf pub on Roker Avenue.
It warned that anyone found to be culpable could face a nationwide ban from football matches.
The teenagers have been released on bail and banned from the Stadium of Light for three months.
Insp Steve Prested said Northumbria Police had taken "swift" action to make the arrests and patrols would be stepped up ahead of Sunderland's home match with Hull City on Friday.
