A Saint John police sergeant has had his criminal case brought to an end after Crown prosecutors decided to withdraw two charges that had been levelled against him by a police oversight body.

The Crown withdrew charges on Jan. 8 of sexual assault and breach of public trust that had been laid against the officer last November by the Serious Incident Response Team.

The group, also known as SIRT, investigates all matters that involve death, serious injury, sexual assault, intimate partner violence or other matters that may have arisen from the actions of any police officer on or off duty in New Brunswick.

SIRT director Erin Nauss said in a summary report that in February 2025, the agency received a referral from the Saint John Police Force regarding “an historical allegation” of sexual assault that was committed by one of its members. CBC News is not naming the officer.
