The PSNI say lives could have been lost after a crowd of youths hurled stones and rubble at traffic around the Harbour Highway last night (Thursday February 16).
A PSNI spokesperson said police had received “a number of complaints” regarding youths at approximately 6.20pm.
The latest incident comes less that the week after a bus was stoned on the town’s Upper Cairncastle Road, shattering one of its windows.
Pictures of the vehicles stoned on the Harbour Highway showed damage to a windscreen and damage to bodywork.
Motorists are being advised to exercise caution when entering or leaving the Larne Harbour terminal and around the Coastguard Road and Ballymena Road areas, and police have stepped up patrols in the area.
Issuing a strong warning to those involved, Inspector Martin Ruddy called their actions “absolute madness.”
He said: “If any of those drivers had lost control of their vehicles, some of which were heavy good lorries, then someone could have easily lost their lives. I am appealing to parents to make sure they know what their children are up to and to speak to them about the very real dangers of engaging in this sort of behaviour.
“Had any of those drivers lost control of their vehicles because they couldn’t see through a damaged windscreen then the people responsible would be facing some very serious charges.”
Anyone with information can contact police on 101 quoting reference 1093 16/02/17.
