A Calgary police officer is charged with assault, after an internal investigation, in connection with an on-duty incident that happened last year.

A taxi driver in the downtown area approached the officer and asked for assistance on Tuesday, January 27, 2009.

The driver told the officer that a domestic situation was developing in the back of his car.

The officer had an interaction with the female passenger, which led to an investigation and the findings were forwarded to the Edmonton Crown Prosecutor's Office for review.

The Edmonton Crown advised a charge of assault was warranted as a result of that review.

The officer is currently assigned to an administrative position and will remain there until criminal proceedings are complete.

The officer's name is not being released because the charge was laid as a result of the member's execution of his duties.
