Schools in The Pas, Man., were in lockdown mode over the lunch hour as RCMP investigated reports of a gun incident in the northern community.

RCMP say they first received a call just after 11 a.m. about two males walking around the Opaskwayak Cree Nation with a firearm.

Officers arrested two male youths and recovered an air pistol, according to police.

But then a second report came in about a firearm, and that prompted police to ask local schools and businesses to be in lockdown as a precaution.

Doug Long, superintendent with the Kelsey School Division, told CBC News he received a call from the RCMP at 11:50 a.m. Thursday, asking that all five of the community's schools be placed in lockdown as a precautionary measure.

Students could not leave for lunch as a result, Long said.

"What they've done with any kids that have any medical conditions, they've been made sure that they've been fed," he said.

RCMP said schools in The Pas and the First Nation were allowed to reopen just after 1 p.m., once investigators determined there was "no longer an active threat to the public."

Police did not release specific details about the second incident.

Long said he could only recall one other time, at least five years ago, when schools in The Pas were in lockdown.

"Very unusual, and they've always been external — something out in the community that's not been proven to be reality," he said.
