The principal of Ayr Hill National School in Ramelton says staff and pupils have been left distressed after a number of vandalism attacks at the school.
In the most recent incident, which happened last weekend, what's believed to be human excrement was left in a classroom.
On a previous occasion, kerbstones were ripped up from a grave in the churchyard adjacent to the school, and used to break windows.
Milford gardai are investigating, and the school authorities are now planning to enhance security and erect cameras.
On today's Shaun Doherty Show, principal Sandra Moore said they have no idea why the school is being targetted in this way........
