Nova Scotia's Serious Incident Response Team is investigating an allegation of domestic violence against a Sackville-area RCMP officer.
Police said they received a 911 call just after midnight on Saturday from a woman who alleged her common-law spouse assaulted her at a home in Beaver Bank, N.S.
They said there were several people in the home at the time.
The Mountie was arrested, but no charges have been laid and he was released on conditions to appear in Dartmouth provincial court in February.
It's the second time this week the SIRT team has had to investifate an allegation of domestic violence against a Halifax-area police officer.
On Thursday SIRT said it received a call from a woman who alleged that her husband, a member of the Halifax Regional Police, assaulted her.
SIRT is responsible for investigating all serious incidents involving police in Nova Scotia, whether or not there is an allegation of wrongdoing.
It is required to file a public report within three months after concluding its investigation.
