Toronto police are investigating after three separate shootings left one man dead in Scarborough, and four others injured.

Paramedics say they were called to a scene near Markham and Ellesmere Roads at about 4:20 a.m. on Sunday. They arrived to find a 28-year-old man with multiple gunshot wounds. He was transported to a trauma centre and later pronounced dead, police say.

The incident was one of three overnight shootings in the city.

Two seriously injured in downtown shooting

Three people, including a man and woman in their 20s, were seriously injured after gunfire broke out on Niagara Street, west of Bathurst Street at around 2:30 a.m.

Police say a bullet grazed a man’s head and woman was shot in the leg. Investigators added that several drivers and pedestrians were nearly hit by gunfire. Several cars and taxi cabs were also struck by bullets.

A third victim was later located near Bathurst and Dupont Streets with serious injuries. Police were investigating whether the victim was connected to the shooting, but later determined he was not.

Investigators say multiple people were arrested near the shooting scene in connection with a stolen vehicle, but police did not say if the two incidents are connected.
