Following the trouble surrounding Saturday's Ballymena v. Coleraine football match, police are now studying extensive video footage to track down the culprits.
They say the majority of fans were well-behaved, but that a small minority was intent on causing trouble and starting fights.
Ballymena lost the quarter-final to Coleraine by 4 goals to nil.
Chief Inspector Stephen McCauley told Q Radio's Roger Donnelly he's very disappointed by the violence:
Man injured after house and three vehicles set alight in Co Antrim
IT system for Northern Ireland schools ‘largely restored’ following cyber attack
£100 home heating oil grant to be paid out by ‘summer at earliest’
Arrest made after hot water thrown over man at Co Tyrone court
Stormont urged to address ‘catastrophe’ in hospital emergency departments
