Police cars and vehicles belonging to members of the public were damaged during a disturbance in south Belfast on Monday night.
The disorder at Broadway roundabout has been described as “particularly protracted” by police.
“Petrol and paint bombs were thrown at officers and vehicles by groups of up to 50 young people,” Ch Supt Jeremy Lindsay.
“The windscreens of three cars were shattered and splattered with paint with some damage also caused to our police vehicles.”
No injuries to police officers or members of the public have been reported.
Ch Supt Lindsay said that police will continue to patrol the area on Tuesday night to prevent anti-social or disorderly behaviour and detect those involved in Monday night’s trouble.
“I would urge the young people who have been involved and their parents or guardians to seriously consider the impact of their actions on the local community, but also on their own futures,” he added.
“These actions have serious consequences. My message is simple, walk away and don’t get involved in any trouble.
“I want to thank local community representatives who worked with us to restore calm and minimise the impact on the local community.”
