A Waterloo Regional Police officer faces five criminal charges and an internal police review.

Police said Monday that the patrol officer has been charged with three counts of uttering a threat, and one count apiece of assault and mischief.

The charges relate to a family-related matter which occurred while the officer was off-duty, police said.

The officer was identified as an officer with 11 years of experience with Waterloo Regional Police, who is currently assigned to North Division – which covers Waterloo and northern parts of Kitchener.

Police did not release their name or gender, citing the possibility that doing so could identify the alleged victim in the case.
