Nova Scotia’s Serious Incident Response Team has arrested a Halifax Regional Police officer after investigating a sexual assault complaint.

In early November, SIRT received a complaint from a woman alleging she had been sexually assaulted by a male police officer.

SIRT conducted an investigation into the case, which led to today’s arrest of the officer in question.

The officer, who has not been named, has been in the force for four years. The alleged incident occurred while he was off duty.

"It is an allegation of sexual assault. The circumstances are such that these two people were known to each other at the time, and it relates to off-duty conduct," says Ron MacDonald, the director of SIRT.

The officer has been released from custody on a promise to appear in provincial court on Feb. 13.

He has also been ordered to have no contact with witnesses or the complainant, and is not allowed to have a gun or consume alcohol.

SIRT is responsible for investigating all serious incidents involving police in Nova Scotia, which includes allegations of sexual assault.
