LONDON, Ont. -- A London, Ont., psychiatrist accused of making secret video-recordings of female patients while they underwent physical examinations is facing 40 new charges.

Police say that brings the total number of charges faced by Dr. Stanley Dobrowolski to 43.

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.

The investigation led officers to execute a search warrant at the College of Physicians and Surgeons of Ontario.

Police say they discovered additional incidents during an examination of computers and electronic storage devices seized by the college from Dobrowolski's office.

After a public appeal asking women who had prior contact with Dobrowolski to come forward, police say 19 women provided information that led to the psychiatrist being re-arrested and new charges laid Monday.

The charges against Dobrowolski now include 18 counts of sexual assault, 10 counts of voyeurism, one count of child exploitation, one count of producing child pornography and one count of possessing child pornography.

Police say the child exploitation and child pornography charges are related to incidents involving a 17-year-old.

Police say they've referred 28 cases of potential professional misconduct to the College of Physicians and Surgeons of Ontario, with the consent of the women involved.

Dobrowolski was suspended by the regulatory body on Oct. 12.
