Police worry gynecologist Dr. Nikita Levy filmed underage patients Police say former patients of an ex-Johns Hopkins gynecologist believed to have committed suicide were violated by him with a video camera. The invasion of privacy could be worse than first reported, CBS Baltimore station WJZ-TV reports. Numerous patients at Johns Hopkins may be victims, and some of them are voicing disgust and outrage. Meanwhile, investigators have growing concerns and are checking to see if Dr. Nikita Levy may have recorded underage patients. Baltimore City police have set up a tipline. Federal authorities are actively involved in the investigation of Levy. The gynecologist was fired earlier this month and was accused of secretly taking pictures and video of his patients during examinations. "I just can't believe it," said patient Tracy Williams. What was he doing with the pictures and video? That's a big unknown. Some gynecology fetish porn claims to feature videos by real doctors. In a statement, Johns Hopkins calls the invasion of privacy intolerable, saying Levy's behavior violates their code of conduct and everything it stands for. Dr. Levy was the sweetest person. This is all- this is just shocking," patient Jessica Wims said. Wims said Levy saved her life when she suffered complications from childbirth. She's outraged with Johns Hopkins for failing to notify patients when the investigation started two weeks ago. To find out the way we did, that hurt. Hopkins didn't send out anything. I had to find out on the news, from family. It's not fair. I've been going to him 11 years," she said. Levy is believed to have committed suicide this week at his home in Towson. Patients may never get the answers they want. I don't know if one of the videos have me on there or not. I don't know, but I can't help from sitting here not thinking about it," Williams said. Legal experts expect this investigation to lead to numerous civil lawsuits.
