A group of men and women visited Leyland Methodist Junior School in Canberra Road over the weekend (December 5 and 6), reportedly arriving in the evenings and not leaving until the early hours of the morning.
While at the school the vandals trashed a marque which was built "for the children's educational needs", leaving behind empty alcohol bottles, drug paraphernalia, cigarette ends and gas canisters.
A child's scooter was also stolen by the group - an incident which police say was caught on CCTV.
