Five men who were denied entry to a bar in Ballymena are reported to have begun throwing bricks and bottles last night.
Police in Ballymena are appealing for witnesses following a number of suspected linked incidents in the town.
At around 3am police received a report of windows having been smashed at a property on Market Road.
And shortly before 5am, a man used a baseball bat to smash the windows of a car in the Dicksons Hill area. The culprit made off in a red car with others on board.
Damage was also caused to windows of a house in Glenshesk Drive.
Sergeant Neil Hewat said shortly before midnight officers responded to a report of a disturbance at licenced premises on Ballymoney Street, and they are now looking at possible links with other incidents.
“We believe all these incidents are linked and we would be keen to speak to anyone who witnessed what happened or could shed further light on those involved.
“Please contact us on 101 and quote reference 1806 of October 31st. Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime,” he added.
