OTTAWA - A Quebec court has ordered suspended senator Patrick Brazeau to go to rehab for two months after he was arrested Monday for allegedly being drunk behind the wheel of a parked car with a knife in the vehicle.

Crown attorney Sylvain Petitclerc says Brazeau will be released Wednesday into the care of a rehabilitation facility in Sherbrooke, Que.

The senator faces three new charges:

-- having had the care or control of a motor vehicle while his ability to operate the vehicle was impaired by alcohol or a drug;

-- having had the care or control of a motor vehicle having consumed alcohol in such a quantity that his blood exceeded 80 ml of alcohol per 100 ml of blood; and,

-- breach of conditions for having possession of a weapon.

Petitclerc says he'll remain in rehab until Dec. 8, the date of his next court appearance on the latest charges, but his therapy may continue for up to two years.

The senator spent the night in custody after a police officer who spotted Brazeau alone in a car reported smelling alcohol on his breath and finding a knife in the car.

Gatineau police spokesman Const. Pierre Lanthier says Brazeau was arrested after he blew twice the legal limit during a roadside breathalyzer test. Police say he also failed a second breathalyzer test at the police station.
