A Halifax Regional Police officer accused of sexual assault and breaching a court undertaking is facing an additional charge.

Police say Const. Chris Mosher, 30, has been charged with impaired operation of a motor vehicle in connection with an alleged incident in Eastern Passage on July 7.

RCMP launched an investigation that night after receiving a complaint from someone in the community.

On Oct. 29, Mosher was charged with two counts of breaching his undertaking by drinking outside of his residence, in connection with the alleged incident on July 7.

Now, police say he is facing an additional charge of impaired operation of a motor vehicle.

He is due to appear in Dartmouth provincial court on Nov. 30.

Mosher is already facing two counts of breaching a court undertaking after he was accused of drinking outside of his home and being in the presence of a woman who is not a relative.

Those charges were related to an incident alleged to have occurred in Lunenburg on Aug. 22.

Mosher was also charged in February with sexual assault and administering a noxious thing with intent to aggrieve after an alleged incident in November, 2012.

Nova Scotia’s Serious Incident Response Team started investigating Mosher after receiving a complaint from a woman who said a police officer had sexually assaulted her.

Mosher, a four-year member of the force, has been suspended from the Halifax Regional Police without pay or benefits.
