Nova Scotia’s Serious Incident Response Team has released a summary report of two separate investigations.

One report deals with a referral from Aug. 7 involving an allegation of domestic violence against a Lunenburg District RCMP officer.

The incidents are alleged to have taken place between December 2010 and Aug. 7, 2012.

SIRT laid four charges against the officer, whose name is prohibited from publication by a court order, in August.

The charges include assault, sexual assault, uttering threats, and careless use of a firearm.

The officer is due to appear in Bridgewater provincial court on Jan. 4.

A second investigation conducted by SIRT has dismissed the complaint of a woman from Indian Brook, who alleged an RCMP officer broke her arm while she was being arrested.

According to the report, the woman was intoxicated at the time of the incident and couldn’t remember the event.

Further investigation found the woman’s arm was likely broken in a fall before her contact with police.

"No one is able to say what caused the arm injury here, including the injured party," said Ron MacDonald, SIRT's independent director, in the report.

"An examination of the totality of the circumstances leads to the conclusion that the woman injured her arm earlier in the day. There are no grounds to consider charges against any police officer in this matter."

SIRT is responsible for investigating all serious incidents involving police in Nova Scotia, whether or not there is an allegation of wrongdoing.
