Twenty-six more women have come forward alleging a doctor sexually assaulted them while they were under anesthetic, and police warned Thursday there could be more victims.

Anesthesiologist George Doodnaught was already facing three counts of sexual assault before police announced the additional 26 charges.

North York General Hospital said 25 of those new charges relate to assaults alleged to have occurred at the hospital during surgical procedures.

“We are extremely concerned that this number of people has come forward to police with allegations and we understand this is a difficult process for those patients and their families,” hospital president and CEO Bonnie Adamson said in statement.

“These allegations relate to one physician who is no longer working at the hospital. The allegations have not been proven in court.”

The Toronto man, 61, was charged in March with allegedly sexually assaulting three female patients during surgeries performed at North York General.

One of the alleged assaults took place in June 1992 and the rest between 2006 and this past February, police said. It is alleged one assault took place in September 2009 at the Rice Medicine Professional Corp. in Toronto.
