Police officer in Gatineau, Que., shot in leg after responding to bush party

GATINEAU, Que. - Police in Gatineau, Que., say a 20-year-old man arrested after an officer was shot in the leg isn't the one who wounded her.

Investigators say the man — who was arrested this morning while trying to leave an area cordoned off by police — isn't a suspect in the incident that occurred last night along the Gatineau River.

He remains in custody on unrelated charges while police continue their hunt for a suspect.

Police say the officer was responding to a call about a bush party involving nearly 20 people when she was struck by a bullet in the leg.

The officer has since undergone surgery and police say she is recovering.

Investigators briefly detained about 30 witnesses, who have been released. (CFRA)
