Police are investigating a shooting at a North York apartment building that left a 16-year-old boy dead.

Officers were called to a building at 30 Falstaff Avenue, near Jane Street, at around 1 a.m. after multiple residents reported hearing gunshots.

When police arrived, they found a male in a stairwell suffering from apparent gunshot wounds.

The victim was pronounced dead at the scene.

Investigators formally identified him late Thursday as Hanad Ali of Toronto, though earlier in the day family and friends identified him as Hanad Abdullahi. 

Police say three suspects, who appeared to be in their early 20s, fled the area in a dark-coloured Honda.

Homicide detectives, the coroner, and forensic officers were on-scene at the building on Thursday morning.

Investigators are reviewing video surveillance footage from the area.

A distraught young woman, who identified herself as a friend of the victim, spoke to reporters on Thursday, criticizing management for a lack of security in the building.

"What is the point of putting security in the building if they are never here," she yelled. He was a kid."

The boy's mother told CTV News Toronto that her son was playing video games at another unit in the building until 12:30 a.m.

She said he was on his way back to their apartment when he was shot in the stairwell.
