OTTAWA - Three people -- including a 14-year-old girl and a 17-year-old boy -- are facing charges following a double shooting and stabbing in Ottawa.

Police say officers responding to a call early Saturday found three males with non-life threatening injuries -- one had been stabbed in the abdomen, the others had been shot. Two were taken to hospital and one refused medical treatment.

They say a loaded firearm was seized and several suspects were taken into custody.

A 14-year-old Gatineau, Que., girl is charged with several weapons offences -- including careless use of a firearm and unauthorized possession of a firearm -- and accessory after the fact.

A 17-year-old Ottawa boy faces charges that include careless use of a firearm, unauthorized possession of a firearm, possession of a loaded firearm, and possession of a firearm obtained by crime.

Investigators also say an 18-year-old Ottawa man is charged with a drug-related offence.
