Police say they have thwarted an attack on a high school in Toronto on the 27th anniversary of the massacre at Polytechnique Montreal.
Toronto police say they received a tip from the public about a threat against a school, which they later identified as Oakwood Collegiate Institute.
Det. Len Nicholson told Toronto news station CP24 that the tip came from the U.S. west coast, where a person saw the threat on a blogging site.
They say they seized a machete, a hatchet, two swords, four knives and arrows after conducting a search warrant on a home Tuesday.
They allege the plan was to take place later that day at the school.
A 17-year-old boy has been charged with uttering threats of bodily harm and uttering death threats, and police say he appeared in court Tuesday.
