Authorities have given the all-clear after a bomb scare at White City School forced the evacuation of the building Monday morning.
RCMP say the school was evacuated as a precaution after several students learned through an online chatroom that there may be an explosive device in the building.
About 700 students were evacuated to the town's community centre and the local arena.
Students and staff were allowed back into the school at around 1:30 p.m. after RCMP explosive disposal and canine units determined there was no threat.
