LONDON, Ont. - Police say they have found seven more incidents in which a London psychiatrist allegedly made secret video-recordings of female patients while they underwent physical examinations.

Dr. Stanley Dobrowolski was charged last November with two counts of sexual assault and one count of voyeurism in connection with alleged incidents at his London office.

Investigators say they discovered additional incidents during an examination of computers and electronic storage devices seized from the office in the southwestern Ontario city.

Police allege the videos were recorded between 2007 and October 2012 at the psychiatrist's office.

The investigation has also led officers to execute a search warrant at the College of Physicians and Surgeons of Ontario. Dobrowolski was suspended by the regulatory body on Oct. 12.

Police say they are working to identify the women involved in the incidents.
