Toronto police say they have charged a doctor with sexually assaulting a patient.

They say investigators received a complaint about an incident that occurred at a doctor's clinic in the city's northwest on Dec. 20.

They allege the 58-year-old doctor sexually assaulted a 40-year-old woman while conducting a physical examination.

A week later police arrested the doctor, who is from Toronto, and he appeared in court the same day.

The doctor has been charged with one count of sexual assault.

The charge has not been proven in court.
