North Bay police at Chippewa Secondary School. Sept. 23/20 (Eric Taschner/CTV Northern Ontario)

A North Bay youth is facing drug trafficking charges after a medical emergency sent a local high school into a 'hold and secure' last month.

The doors were locked and no one was able to leave Chippewa Secondary School the afternoon of Sept. 23 and police and paramedics were called to the scene.

North Bay Police’s school liaison officer determined that three young people needed to seek medical treatment.

The investigation found that a young person, who is not a student from the school, allegedly sold suspected Xanax to students at an offsite location.

Police seized approximately 11 suspected Xanax tablets as part of the investigation.

The accused was arrested on Sept. 28 and was later released from police custody.

The youth will appear at the North Bay Courthouse on Nov. 18.

In accordance with Canada’s Youth Criminal Justice Act, police will not be releasing the name of the youth or any other information.
