Police reported that on Monday morning, a high school student in Bedford, Nova Scotia, identified only as a Canadian national, was taken into custody after stabbing two school staff members and himself.

The incident occurred in an administrative office at Charles P. Allen High School, where the student brandished a knife, resulting in the hospitalization of both staff members and the student.

“He was yelling things like, ‘My life doesn’t matter. Your life doesn’t matter,’ and yelling how diplomas don’t mean anything,” student Dax Thompson told CTV News.

The teen was in an office due to “concern with the student,” said Halifax ed spokeswoman Lindsey Bunin.

Bunin reported that the student fled the school following the stabbing, but was swiftly apprehended by police officers.

A security guard was “chasing after him and then there were five police cars that came and they were surrounding him,” 10th-grader Raghad Ghazal said. “I was kind of shocked.”

According to CBC, Allen High is the biggest school in Nova Scotia, accommodating approximately 1,700 students in grades 10 through 12. Following the stabbing incident, the school remained closed for the rest of the day, and no announcement has been made regarding the date of resumption of classes.
