Police have charged a Chatham-Kent teen with assault with a weapon after a video circulated that allegedly showed a student with a gun in a Leamington-area classroom.

Leamington OPP say they got information about a video circulating that showed a student with what they believe is a firearm. Officers then met with school staff to identify the "involved parties" and make sure staff and students were safe, police say.

Officers arrested a 17-year-old from Chatham-Kent before school on Friday, police say. The person is been charged with assault with a weapon, possession of a weapon for dangerous purposes and mischief under $5,000.

The teen was released from custody and will appear in Windsor court at a later date.

Police say no one was injured and there are no ongoing safety concerns. But they encourage students and staff to report any similar incidents to school staff and police.

Police didn't respond to request for comments Friday, and didn't specify the school.
