Incidents include missiles being thrown at houses, fireworks being thrown into doorways, the skateboard ramp being set alight and eggs being thrown at houses and at a coach load of senior citizens returning home after a day out.
Police say that all the incidents have involved a large mixed sex group of youths known to frequent the town centre.
Several names have been taken and the police are in the process of compiling evidence to support a charge of public nuisance.
The police advise parents to keep their children under control and to be aware of their whereabouts, especially with Hallowe'en approaching.
