The Toronto Police are not answering questions about the criminal investigation that led to a shooting that sent two people to hospital early Sunday morning.

The incident, which has sparked an investigation from the province's police watchdog, occurred at about 3:30 a.m. at Pharmacy and Conroy Avenue after both Toronto Police and York Regional Police stopped a silver Pontiac Grand Am.

According to CTV's Ashley Rowe, the driver of the vehicle sped up after he and his passenger realized they were being followed by police. The car then careened into a tree, and became boxed in by unmarked police cars, Rowe said.

Police confirmed that the male driver of the vehicle was shot shortly after he stepped out of his car.

According to Eleanor Dean, who lives across the street, emegency workers arrived shortly after.

"The cops were here really fast and the ambulance, they took two people away," she told CTV Toronto

Shane Maracle, 32, and the vehicle's lone passenger were transported to hospital. Both are under arrest, police told CTV Toronto. The SIU however has not said whether the police have charged the pair.

Officials said Maracle was wanted in a separate criminal investigation.

So far, details leading up to the police investigation are still unknown. An SIU spokesperson speaking from the scene of the incident said the Grand Am did not stop when police attempted to lawfully do so.

"The vehicle would not stop when officers attempted to make a lawful stop and that's part of the investigation," Jasbir Brar said.

In a statement released Sunday, the SIU said it is looking into the man's "gunshot injuries." The SIU is not reviewing any injuries the passenger may have sustained, said police.

According to investigators, Maracle is not the owner of the car.

Six investigators and three forensic specialists are investigating Sunday morning's altercation. They are interviewing neighbours however many say they didn't hear anything.

"We woke up and went outside to see how the weather was like and was like ‘wow, there's tape in front of our door," Valerie Brunet told CTV Toronto.
