A 17-year-old is facing mischief charges in relation to prank 911 calls made last weekend in Mississauga.

Peel police arrested and charged a suspect earlier this week after four calls were allegedly made last Saturday to Monday, each reporting incidents of violence in a different area in the city.

The calls, police said, consisted of a fight involving weapons. Officers descended upon each scene only to discover the reports were false.

"These kind of calls are an enormous waste of time and resources," said Peel police spokesperson Rachel Gibbs, adding that some of the calls even drew the force's tactical unit because the reports claimed there were weapons involved.
