The Police Service of Northern Ireland has released photos of four suspects they want the public to help identify after four nights of unrest in Northern Ireland.
The disorder started on Monday after a peaceful protest over an alleged sexual assault in the County Antrim town but has spread to other areas.
Police said 63 of their officers have been injured over four nights of violence after coming under “sustained attack with heavy masonry and fireworks”.
ACC Ryan Henderson said: “It is in all of our interests and in the interests of justice that those responsible are dealt with.”
The first protest was organised hours after two teenage boys appeared before Coleraine Magistrates’ Court.
They spoke through an interpreter in Romanian to confirm their names and ages. Their solicitor said they would be denying the charges.
“In releasing these images, I am asking the wider community to step forward and help us to identify these people,” ACC Henderson told a press conference on Friday.
Police have made a total of 17 arrested following disorder in various parts of Northern Ireland.
His message to those involved was: “We’re actively taking steps to find you and we will bring you to justice.”
“Our public order inquiry team has been working night and day to identify those involved,” he added.
He also said police are investigating “those posting hate on social media”.
The worst of the disorder was in Ballymena, but unrest also spread to other towns.
In Portadown, County Armagh, on Thursday a crowd pulled bricks and masonry from a derelict building which they threw at police.
ACC Henderson said: “police came under significant and sustained attack from rioters. It was clear that those involved were intent on destroying homes and businesses within the town and on attacking police.”
“The police lines came under attack from heavy masonry, fireworks, petrol bombs and beer kegs,” he added.
In Larne, masked youths attacked a leisure centre and set it on fire on Wednesday. The centre had been providing emergency shelter for families following the clashes earlier this week.
The home of a family with three children was set on fire in Coleraine on Thursday night, in what ACC Henderson called: “an awful, hate-motivated attack”.
The constable appealed for “calm” over the coming weekend and said there will be a large police presence across Northern Ireland.
“For those thinking about causing disorder or coming to watch it, stay away, there will be consequences.”
