Montreal police are looking for a new suspect in connection with the city's 30th murder.

They are asking for the public's help in tracking down Patrick Tshitenge-Masuku.

He is described as a 6'2", 185 pound (1.88 m, 84 kg) man with curly black hair, black eyes, dark skin and a scar on his chin.

Early Saturday morning a 22-year-old man was repeatedly stabbed in the chest while inside Tribe Hyperclub.

He was rushed to hospital, but doctors were not able to save his life.

At the time of the attack, police arrested a 20-year-old man and interrogated him throughout the weekend.

He was considered a suspect, but at this point police are not recommending charges.

Police say the victim was "known to police," but they are not identifying him yet.
