Ottawa police have charged a teenager with first-degree murder in Ottawa's first homicide of 2012.

Ahmed Hafizi, 18, is charged in the downtown Ottawa death of 24-year-old Navid Niran on Jan. 22.

Police said the victim was known to them.

Paramedics said they had been called to a report of a stabbing outside a Dalhousie Street nightclub around 2:30 a.m.

Niran was taken to hospital, where he later died.

Hafizi will appear in court Friday.
