DOWNEY - A male registered nurse at Kaiser Permanente Medical Center in Downey has been arrested and charged with sexually assaulting hospital patients who were recovering from surgical procedures. Dean Trinh Ngo, 35, was arrested last Thursday and charged with four felony counts of sexual battery.

The Downey Police Department launched an investigation May 8 when a woman reported she was the victim of a sexual assault at the Kaiser hospital.

The woman said she was recovering from a surgical procedure when the assault took place.

Downey detectives, working with Kaiser Permanente staff, identified Ngo as a suspect. He was immediately suspended and placed on administrative leave, police officials said.
