Larne police are asking the community to support the School Watch initiative to protect empty schools during the summer.
Chief Inspector Catherine Magee condemned vandals who damage schools. She said: “Attacks on schools can range from broken windows and graffiti to more serious incidents including arson and burglaries.
“Vandalism is particularly disheartening and it is frustrating to see how these mindless acts affect a school and impact the whole community.
“Schools and hard working pupils do not deserve to see their buildings and facilities damaged.
“If you see suspicious activity around a school, please dial 999 immediately.
“Do not wait and think about it later.”
