Gun found in boy's backpack at Toronto school

A 12-year-old boy has been arrested after allegedly bringing a loaded revolver to a school in northwest Toronto.

The boy was found with a loaded handgun in his backpack on Friday afternoon.

The incident happened at Oakdale Park Middle School, which is in the city's north end, near Jane Street and Sheppard Avenue West.

The boy said he found the gun, put it in his knapsack and brought it to school, police said.

The gun was found during "an altercation," said Const. Tony Vella.

Chris Crone, the principal of the school, said he was "shocked" after he found the gun along with another teacher. Crone called police immediately afterward.

Police have released few other details, but say the gun is a .38 Colt revolver and that it was loaded at the time.

The child is facing charges including:

- Possession of a firearm.

- Possession of ammunition.

- Careless storage of a firearm.

- Assault.

Crone said he believed security at the school is "sufficient."

"If you look at the American model, with metal detectors and so on, that's not the Canadian model of schooling," he said.

"I believe … this is a safe place to come to school," he added, saying the school is looking to add video cameras and a secure back door.

Parents were sent a letter on Monday informing them that the gun was found. A meeting with parents will be held Wednesday at 6:30 p.m.
