Vandals have smashed more than 50 double glazed windows at a school in west Belfast.
The incident is believed to have happened at the school on the Stewartstown Road at about 1730 BST on Saturday.
Three boys aged about 10 were seen running across fields away from the school towards Willowvale Avenue.
The school will be open on Monday. Police have appealed for anyone with information to contact them.
One of the children seen running away had red hair and was wearing a green, white and orange top.
The two other boys were dressed in white tops and red trousers and had bleached blond hair.
Sinn Fein's Michael Ferguson condemned the incident.
"It is outrageous that at a time when the education budget has been cut by over £7m in the Belfast area that this sort of vandalism is taking place," he said.
