A north Queensland police sergeant accused of being involved in an assault in Cairns has resigned from the service.
The officer from the northern police region was charged with one count of assault occasioning bodily harm following an investigation by Queensland Police.
He resigned from the service on Monday, a statement issued by the Queensland Police Service said.
Police will allege the 43-year-old officer was off-duty when he was involved in an assault at a Cairns home on January 24.
He's due to appear in the Cairns Magistrates Court on February 25.
Queensland Police says while it has a duty to inform the public when an officer is facing criminal charges, this doesn't mean the allegations against the officer have been substantiated.
