Calgary police have laid attempted murder charges against a 17-year-old boy following a dramatic incident at Lester B. Pearson High School in northeast Calgary on Thursday that forced the school into lockdown.
The incident unfolded around 12:05 p.m. when officers responded to reports of a youth armed with a knife on school grounds. According to police, the teen was actively smashing property, making threats toward students and staff, and attempted to stab at least one student during the chaos.
"Officers arrived at the school and moved quickly to apprehend the suspect," a police spokesperson confirmed Friday. "The response time was critical in preventing further harm."
The school was immediately placed under full lockdown as first responders secured the scene. Within minutes of entering the building, officers arrested the suspect and took him into custody without further incident.
One student sustained minor injuries as a result of the alleged assault. No other injuries were reported among students or staff during the incident.
The 17-year-old has been formally charged with attempted murder. The investigation is ongoing, and police have not released additional details about the circumstances leading up to the incident or the suspect's motivations.
The incident has raised concerns among parents and community members about school safety. Lester B. Pearson High School serves hundreds of students in Calgary's northeast and is one of several schools in the area managed by Calgary Public Schools.
This incident comes as schools across Alberta continue to grapple with safety protocols and resource allocation for student protection. Many parents and educators have called for increased support systems, including mental health resources and crisis intervention training for staff.
