Police are investigating the third attack on a Free Presbyterian church in Ballyclare, Co Antrim within the last 12 months.
The most recent incident at the church on the Doagh Road is believed to have happened overnight between 28 and 29 December.
A window was smashed and it is believed a metal bar was used.
Police say they have spoken with community and elected representatives, including street pastors, in relation to anti-social behaviour and criminal damage in the town centre.
In a post on Facebook, a PSNI officer added: “Parents, do you know where your young ones are of an evening? Please have a word before we end up with an arrest charge and court appearance.”
Anyone who saw suspicious activity in the area around Ballyclare Free Presbyterian Church in recent days is asked to contact police on 101.
