A New York City doctor has been charged with allegedly drugging and filming himself sexually assaulting and raping multiple women, including patients in his care.

Gastroenterologist Zhi Alan Cheng, 33, was arraigned on a 50-count indictment Monday for charges related to the alleged rape of three women at his Astoria, Queens apartment and the sexual abuse of three patients at New York-Presbyterian Queens hospital where he worked between June 2020 and December 2022.  

Cheng was originally arrested and terminated from his position in December after a woman reported him to police for allegedly drugging and raping her at his apartment. The new indictment, announced by Queens District Attorney Melinda Katz, also accuses Cheng not only of drugging women in order to rape and sexually assault them, but filmed himself committing the acts.

These videos were recovered by investigators after one alleged victim discovered the recordings in Cheng’s apartment, which included a recording of herself and other women being assaulted, according to the statement released by District Attorney Katz’s office.

Authorities also said investigators discovered narcotics, including fentanyl, ketamine, cocaine, LSD and MDMA and sedatives used in hospitals, such as propofol and sevoflurane, when searching Cheng’s apartment.

The evidence listed by the D.A.’s office includes video of Cheng at the hospital groping a 19-year-old patient, a “seriously ill” 47-year-old patient and engaging in sexual intercourse and abuse with women at his apartment, all of whom were unconscious and sedated.

While he is currently being charged based on video evidence depicting the abuse of six women, the D.A. alleges that further video evidence indicates Cheng assaulted a number of other women in Westchester County, Manhattan, Las Vegas, in and around San Francisco and Thailand.
