LONDON, Ont. -- A 22-year-old London man has been charged with second-degree murder in connection with a shooting in the southwestern Ontario city.

Officers were called to the downtown area (around Richmond Street and King Street) just after 3 a.m. Sunday when gunshots were reported.

Police say two men were shot in the incident, which is London's fifth homicide this year.

Terrell Johnson, 21, died of his injuries in hospital Sunday while an unidentified 28-year-old man suffered non-life-threatening injuries.

Police have arrested seven people in the incident, though three have since been released.

Joshua Carter is charged with one count of second-degree murder and has been remanded into custody.

Police say there is no evidence the shooting is gang-related or connected to homecoming celebrations at Western University.
