Four people - including two Peel Regional Police officers - were injured following a weapons call in Mississauga.
Officers were called to Elia Avenue, near Eglinton and Hurontario just before 2:30 Saturday afternoon.
That's when one of the suspects - armed with a baseball bat - struck one of the officers in the head.
Peel paramedics told CP24 all the injuries are minor.
It's not known how the three others were hurt.
