Three teenage boys have been detained after a perceived threat sent the Massey-Vanier High School in Cowansville into lockdown Thursday morning.

The Sûreté du Québec said two of the boys were inside the school when they were detained. The other was stopped off of school property.

None of the individuals had a weapon at the time police took them in.

The SQ said it received information around 9 a.m. that prompted them to order the lockdown as a preventative measure.

"It was concerning information, related to the safety of people in a school in Cowansville," said Aurélie Guindon, am SQ spokesperson.

The lockdown ended just after 11 a.m. The SQ said that on-site checks suggest there was no danger to the people inside.

About 1,300 students attend Massey-Vanier High School, which is comprised of students from both the Val-des-Cerfs and the Eastern Townships school boards.

In a Facebook post, the Eastern Townships School Board said it received information there was a "perceived threat outside of the school" prior to the lockdown.

"We can now assure parents that all students and staff are safe and secure, and the authorities are on site managing the situation," the post said.

That information was posted about an hour after the French-language Val-des-Cerfs board alerted parents to what was going on.

Michael Murray, chair of the Eastern Townships School Board, said the priority was to ensure staff and students in the school were safe.

The board didn't want to "unduly alarm people" by issuing false information, he said.

"One of the unfortunate aspects of social media is that there can be a great deal of information posted there that is not verified, not accurate and may, in fact, be quite erroneous. But we do avoid posting anything that we're not sure is accurate."

For both English- and French-language students, the school was to remain open Thursday afternoon, with classes proceeding as usual.

However, many parents came to the school to pick up their children when the lockdown was lifted and, on the French side, about 90 per cent of the students left for the day.

Cowansville is about 90 kilometres east of Montreal.
