Toronto police say they’ve found evidence of a gun being fired at an Etobicoke school.

Officers were called to Silverthorn Collegiate Institute near Burnhamthorpe Road and Mill Road just before 4 p.m. for reports of two people with a gun.

The school was placed in lockdown while police searched and cleared the premises.

Dozens of parents lined the sidewalk waiting for their children to be let out of the school. Parents told CityNews that students were at the school after hours for a Grade 8 open house and a basketball game.

“It was really scary,” one student told CityNews. “We went and hid upstairs,” another student added.
