Dr. Steve Leong, 58, was arrested at his home in Arcadia last Friday. He is accused of sexually assaulting four different Spanish-speaking women from December 2010 to as recent as February.
The victims claim Leong took them into an examination room inside the Claude Hudson Medical Center and forcefully kissed and grabbed them. Medical officials contacted investigators on May 20 after one of the alleged victims first reported the incident.
The Los Angeles City Attorney's Office has filed six misdemeanor counts of false imprisonment, four misdemeanor counts of sexual battery and five misdemeanor counts of battery.
"Mr. Leong is accused of basically bringing the women into his examination room, kissing and grabbing them inside the room," said L.A. County Sheriff's Sgt. Richard Ruiz.
Leong, who practiced internal medicine, was released Tuesday after posting $150,000 bail.
There was no answer at Leong's Arcadia home Wednesday.
An L.A. County Department of Public Health spokesperson said Leong was placed on administrative leave.
Detectives say Leong has not previously been accused of anything during his career.
Anyone with information is urged to call the Los Angeles Sheriff's Department Special Victims Bureau at (877) 710-LASD.
