Two young people are facing multiple weapons-related charges after RCMP found a duffel bag containing several guns and ammunition in a wooded area close to Millwood High School in Middle Sackville.

RCMP say one of the youths was arrested at the scene and another was arrested nearby shortly afterward. The high school was locked down for part of Tuesday afternoon.

​Cpl. Jennifer Clarke says the investigation is ongoing. There were no injuries reported.

She would not specify what type of firearms were found, but said there was a mix of real weapons and replicas in the bag and none on the people arrested.

"We believe the two individuals arrested put it there prior to their arrest," Clarke said.

Clarke wasn't able to say if the youth arrested were students. Both are set to appear in Halifax provincial court Wednesday morning.

Police say they are looking into whether there was a planned school shooting.

"To find firearms in the woods and arrest two people with weapons offences near a school, one would have to conclude it's a possibility," she said.

The lockdown at Millwood High School was lifted following the arrests.

Clarke said students at nearby Millwood Elementary were also on hold-and-secure status, meaning no one could enter or leave the building, but the students were allowed to move around within the school. The hold-and-secure was also lifted.

Lockview High School in Fall River also went into lockdown briefly Tuesday afternoon. Police were on scene at Lockview following another weapons complaint, but no arrests or weapons were reported. Clarke confirmed police are investigating if the two incidents are related.

"If they're connected, we're certainly looking into that possibility," she said.

Parents notified via phone and email

Doug Hadley, spokesman for the Halifax Regional School Board, said it is adding resources to the school Wednesday, including councillors for staff and students who might want to talk to someone.

He also said there will be an RCMP school liaison officer at the high school when it opens.

"They are just there for support that the school can rely on," he said. "Just to provide that level of comfort that someone might find in seeing an officer available to them."

Hadley said he doesn't know if the two people under arrest had any direct connection to the schools, or if they just happened to be in the area.

School officials have already started to debrief the incident, Hadley said Tuesday evening.

He said both schools used automated phone messages and emails to notify parents of the lockdown and hold-and-secure and the board was planning to send another email update Tuesday night.
