A 24-year-old Toronto man shot and killed in the city's Riverdale neighbourhood this weekend was previously charged with first-degree murder in a brazen shooting at a downtown Chinese restaurant that left a 31-year-old man dead in November 2014.

Police have released security camera footage of a fatal downtown Toronto shooting that claimed the life of a 31-year-old man in November and are seeking the public's help identifying the suspects involved.

The man who was killed at the Garden Restaurant earlier in November was shot during a fight with a group of men who had minutes before robbed his friend of expensive jewellery.
