No charges will be laid against a male officer with the Halifax Regional Police who was accused of sexually assaulting a woman.

Nova Scotia's Serious Incident Response Team, the group that investigates allegations of police wrongdoing, said the woman filed the complaint in March 2014.

"SIRT interviewed the female the next day. She alleged that a male HRP officer had sexual intercourse with her without her consent," Ron MacDonald, the director of the Serious Incident Response Team, said in a news release Thursday.

The team conducted a forensic investigation of her phone and interviewed several friends, he said.

"Messages retrieved from the phone, and information from those friends, indicated that the female had in fact consented to the encounter with the officer," MacDonald said.

"In a followup interview with the female she acknowledged she did consent. As a result, there were no grounds to consider charges against the officer."

The woman has not been charged with any offence.

"In this case, there was a factor that she had received some advice from her lawyer. When we considered that advice, together with other personal circumstances of the individual, we determined that the public interest did not favour her being charged with the offence," MacDonald added in an interview with CBC News.

He called it a "learning lesson" for the woman.
