TORONTO - Bullets flew at Exhibition Place early Sunday -- many fired by Toronto Police -- as four people were wounded outside a dance club in a wild incident now under investigation by the province's police watchdog.

Ontario's Special Investigations Unit (SIU) says the gunfire erupted around 2:30 a.m. in a parking lot near Muzik Night Club on Saskatchewan Rd., just east of Dufferin St.

"Officers heard gunshots and saw a car leaving the area," the SIU said in a statement on Sunday. "When the car failed to stop, officers discharged gunshots at the car."

The vehicle, a dark-blue Honda, continued for several hundred metres despite being hit at least five times, according to investigators.

The car exited Exhibition Place grounds through the Dufferin Gate, travelled north up Dufferin St., then careened off the road, crashing into a snow bank south of King St. W.

The Honda remained there throughout the day as police and the SIU investigated.
