Sexual Battery Charge Filed Against Fair Oaks Hospital Employee

FAIR OAKS, VA — Fairfax County Police detectives have charged a Gainesville man with sexually assaulting a patient at Fair Oaks Hospital, according to a police release.

Hospital staff contacted police on April 18, after a patient reported he was given a physical exam by the hospital technician who had handed him a gown. At first, the victim thought the man was authorized to conduct the exam, but the victim later told a physician assistant about it, which led to staff calling the police.

A preliminary investigation revealed that 25-year-old Yoshimi Koga Contreras of Gainesville had told the victim to undress. He then performed a physical exam of the victim's body, including his genitals. Koga Contreras is not authorized nor does he have a license to provide medical treatment, according to police.

On Tuesday, police charged Koga Contreras with aggravated sexual battery. After being arrested in Vienna on Thursday, he was taken to the Fairfax County Adult Detention Center and held without bond.

Koga Contreras has been an employee of Fair Oaks Hospital since 2016.
