There were some scary moments at a school near Dundas and Ossington on Wednesday.
Someone dressed as menacing clown was scaring children outside Pope Francis Catholic School.
It's a prank that's becoming more popular. Police say two 15-year-olds were filming a YouTube video. They've been given a warning.
No one was hurt.
There are also reports that threats of so-called "clown attacks" had been made toward eight catholic schools in the city.
A board spokesperson told CTV, letters are being sent home to parents.
