South Los Angeles physician Dr. Kevin Antario Brown, 37, was charged Sept. 4 with additional counts of sexually abusing patients.
Police say Brown now faces 33 counts in alleged molestations involving 12 patients.
Prosecutors say the charges include forcible rape, lewd act upon a child and sexual battery.
Brown was arrested July 8 and initially charged with sexually molesting a female patient and a female undercover police officer who posed as a patient. One of the patients was a 15-year-old girl.
Since his July 8 arrest, 10 other accusers have come forward.
The assaults allegedly took place at Brown's office in the Crenshaw Expo Medical Center located at 3631 Crenshaw Blvd. in Los Angeles.
Brown, the son of Bermuda's premier, has pleaded not guilty on all counts.
