TORONTO -- There were at least three shootings over the course of an hour late Tuesday night, including one that sent two 15-year-old youths to hospital.

The first shooting happened at around 10:45 p.m. on Tuesday outside a housing complex on Grandravine Drive.

Police says that officers who arrived on scene located the two boys with non-life threatening injuries in the parking lot behind the complex.

Multiple shell casings were also found on the roadway.

“Detectives are conducting their investigation in conjunction with the forensic identification unit and we are appealing to any witnesses who may have been in the area at around 10:44 p.m.,” Insp. Paul Rinkoff told CP24 at the scene. “If you saw or heard anything please contact 31 Division investigators or if you prefer to remain anonymous please contact CrimeStoppers.”

About 30 minutes after the first shooting police received another shots fired call, this time in the Don Valley Parkway and Eglinton Avenue area.

Police say that they located two vehicles and a residence with bullet holes at the scene, though no injured parties were found.

At around 11:30 p.m., police were then called to the Kennedy Road and Eglinton Avenue for the third shooting of the night.

Police say that a male victim was located at that scene with a gunshot wound and taken to hospital in non-life threatening condition. The victim is not cooperating with the investigation, police say.

Meanwhile, at around midnight an individual walked into Sunnybrook Hospital with a non-life threatening gunshot wound.

“Investigators are in the process of determining whether that individual is related to this shooting or another shooting during the course of the night,” Rinkoff told CP24 at the Grandravine Drive scene.

No arrests have been made in connection with any of the shootings at this point.
