A 17-year-old Toronto boy has been charged with second-degree murder in the stabbing death of a student who tried to stop a hallway fight at North Albion Collegiate Institute in Etobicoke.

Hamid Aminzada, 19, was stabbed when he tried to intervene in a dispute between two students in the school hallway, Toronto police said Wednesday morning in announcing the arrest.

Aminzada, who was born in Afghanistan and immigrated to Canada from Pakistan with his family two years ago, died in Humber River Hospital.

The teenage suspect was scheduled to appear in court Wednesday. He can’t be identified because of his age.

Police say the suspect turned himself in on Tuesday evening.

Aminzada was stabbed inside the school at around 12:45 p.m.

Donna Quan, director of education at the Toronto District School Board, told reporters outside of North Albion Collegiate Wednesday morning that the Tuesday’s stabbing was an “isolated incident.”

“The school is also a microcosm of the community and an incident like this could happen anywhere,” Quan said.

She said that 93 per cent of students reported have feeling safe at TDSB schools.

Quan stressed the importance of community involvement in keeping schools free from violence and tragedy. She said she would like Toronto schools to bolster relationships between students, teachers and community members so that every one has an “ear to the ground” and feels comfortable reporting anticipated violence.

“Our system has been shaken again by the death of [a] student in one of our schools and we take this event very seriously,” Quan said.

She said she would not support installing metal detectors at school entrances in an effort to keep weapons off of school property.

“I strongly believe that metal detectors are not the answer. It’s about the relationships that we have in our schools,” Quan said.

According to Quan, TDSB staff at North Albion Collegiate will conduct a thorough debriefing of the attack and crisis response once the police investigation has ended.

Toronto police Supt. Ron Taverner, who was also at the Etobicoke high school Wednesday morning, said that three school resource officers were posted at North Albion Collegiate while other officers patrol the area and conduct walk and talks with students coming out of the school.

Taverner wouldn’t comment on the investigation.
