It was a tense Monday afternoon for parents, students and staff at Riverview High School.

A letter was sent out via email from Anglophone East after reports of suspicious activity.

Superintendent Randy MacLEAN stated reports came in just after 3 p.m. on Monday.

A hold and secure went into effect at the school, and dismissal time was delayed.

During a hold and secure, no one is permitted to enter or leave the school.

RCMP launched an investigation, but there’s no word yet if anything was found.
