LOS ANGELES - The Los Angeles Police Department on Tuesday announced that 52 patients of a former University of Southern California gynecologist have filed complaints about his conduct. According to police, the 52 complaints do not constitute a criminal case against Tyndall, who has denied any wrongdoing, because none of the women have filed a police report. The police are looking into the complaints, and if they find any criminal allegations, they could present the case to the Los Angeles County district attorney. Thirty-nine of the 52 complaints come from USC, which set up a hotline for patients to report their experience with Tyndall, Hayes said. As of Tuesday, 27 former patients, including three Chinese graduates of USC, had filed lawsuits against USC and Tyndall.
