The province's police watchdog is investigating an early morning rollover in the city’s west end that sent two teens and a woman to hospital.

The collision took place at around 2:45 a.m. near Dundas Street and Lansdowne Avenue.

According to the Special Investigations Unit, officers attempted to stop a vehicle in the area that had been reported stolen and the vehicle subsequently fled.

The SIU says the driver of the car crashed into a construction site a short time later and the three occupants were able to escape the vehicle before it caught fire.

Paramedics previously told CP24 that two teens and a woman in her 20s were taken to hospital for treatment and their injuries are believed to be non-life-threatening.

The area was shut down on Wednesday morning but has since reopened.

Three investigators and two forensic officers have been assigned to the case.

The SIU is an arm's-length agency that is called in any time a police officer is involved in a death, serious injury or allegations of sexual assault.
