Cape Breton Regional Police are investigating after threats were made towards two schools in Glace Bay, N.S., Friday morning.

Glace Bay High School and Oceanview Education Centre were locked down shortly after 11 a.m. as police and staff were investigating inside.

Police say the schools received letters “indicating a potential threat to the schools.”

There were several worried parents and caretakers outside.

“I have a grandson in there. There's no need of it,” says Jean Pink. “My blood pressure is gone through the roof. There's no need of this at all in this day in age.”

“If someone thought this was funny to do, it's not. Because it's parents that have to suffer too because we don't know what's going on with our kids,” says parent Mike MacKenzie.

Police have determined there is no risk to public safety and students were dismissed at 2 p.m.
