An Ottawa police constable has been charged with impaired driving after he was stopped and arrested in southern Ontario.

Const. Luc Durocher was off duty, police say, when the Niagara Regional Police Service pulled him over Jan. 25.

Police said Durocher was under the influence of alcohol and he was charged with impaired operation of a motor vehicle.

Durocher will appear in court Feb. 22 in St. Catharines, Ont.

He has been reassigned to administrative duties, but charges could be laid by Ottawa police under the Police Services Act.
