A 17-year-old Toronto student has been charged after police say they foiled a potential attack at a local high school to coincide with the anniversary of the massacre at École Polytechnique in Montreal.

Toronto police Det. Len Nicholson said police received a tip on Dec. 1 from someone on the west coast in the United States about a threat posted on a blog that referenced École Polytechnique.

“He mentions in his threat about the Montreal massacre,” Nicholson said.

Investigators later determined the school to be Oakwood Collegiate Institute near Dufferin Street and St. Clair Avenue West. Nicholson said the threat was posted from a Toronto District School Board.

Officers seized a machete, a hatchet, two swords, four knives and arrows from a bow-and-arrow set.

Nicholson said police also seized clothing and computer equipment consistent with an attack.

“In (the suspect’s) threat, he made mention that he was going to hide weapons inside of his clothing to enter into the school to do the attack,” he said, adding the accused retained a lawyer and didn’t speak with officers.

Nicholson said police don’t know the suspect’s motive and investigators believe the accused acted alone. He said police are searching online for similar posts.

Toronto District School Board spokesman Ryan Bird told Global News the teenager was a TDSB student. A letter from Steve Yee, principal of Oakwood Collegiate Institute, was sent home with students Wednesday.

“Some of you may have noticed a police presence at our school yesterday. They were here to investigate a reported threat made toward the school,” the letter read, adding the well-being of staff and students is “a top priority.”

“Earlier that day, officers contacted me to advise that they had arrested a person overnight in relation to that threat. As a result, it was not necessary to disrupt regular school routines. All students and staff are safe.”
