Queens doctor charged with taping sex assaults on unconscious patients

A Queens doctor has been charged with sexually assaulting unconscious patients at his hospital, raping three women at his home — and recording the horrific attacks, authorities said Monday.

Zhi Alan Cheng, a gastroenterologist at New York-Presbyterian Queens, is accused of drugging the women he allegedly raped in his apartment.

Cheng is charged with filming his alleged sexual abuse of the hospital patients, all of whom appear to be unconscious in videos recovered from the suspect.

The videos seized from Cheng depict more than six other women being sexually assaulted, including one at New York-Presbyterian Queens, who authorities have yet been able to identify.

“The recovered evidence compiled paints the picture of a sexual predator of the absolute worst kind, a serial rapist, someone willing to not only violate his sacred professional oath and patients’ trust, but every standard of human decency, as well,” Queens DA Melinda Katz said in a statement. “We will present the facts to a jury and achieve justice for the victims of the horrific assaults captured on video.”

Cheng, 33, of Astoria, was indicted by a grand jury and arraigned on 10 counts of predatory sexual assault, three counts of rape, seven counts of sexual abuse and and four counts of assault.

He was also charged with eight counts of criminal possession of a controlled substance and four counts of criminal possession of a weapon.

If convicted, Cheng faces multiple 25-year-to-life sentences

While in Cheng’s residence, the first victim came across videos depicting her and other women being assaulted by the doctor, officials said. In December, her attorney approached the Queens District Attorney’s office.

Cheng was arrested that month for raping that women and investigators went to work proving the other cases.
