The province's Serious Incident Response Team has arrested a Halifax Regional Police officer who is accused of sexually assaulting a woman.

SIRT says it launched an investigation after receiving a complaint from a woman in early November.

The male officer was arrested on Tuesday and released on conditions, including not having any contact with the alleged victim and not carrying a firearm.

He is scheduled to appear in provincial court on Feb. 13.

The officer is a constable and has been with the force for four years. His name is not being released because the investigation is ongoing and he has not been charged.

A spokesperson for Halifax Regional Police says the department just learned of the arrest and has yet to decide whether the officer will be suspended from active duty.

In a news release, the department says allegations against its officers are "very troubling." It's waiting for more information from SIRT.

SIRT was set up earlier this year to investigate serious incidents involving police. It has investigated 19 cases, and 12 are still active.

Three police officers have been charged with domestic assault since SIRT was formed.
