Two fires at schools in Belfast and County Down are being treated as arson. A temporary building belonging to a building contractor was damaged in the grounds of De La Salle High School on Struell Road in Downpatrick.
It was discovered shortly before 1700 GMT on Saturday and firefighters were called to the scene.
Minor damage was also caused to the Good Shepherd school in the Poleglass area of west Belfast.
