The son of Premier Dr. Ewart Brown faced 10 more charges of sex crimes against four more female patients in a Los Angeles courtroom yesterday after his lawyers failed to throw-out the 23 previous charges.

Last month, Kevin Antario Brown, 37, pleaded not guilty to 23 felony charges of sex crimes against eight female patients.

He remained in custody yesterday on the $4 million bail.

In LA Superior Court yesterday, Brown's lawyers attempted to dismiss the 23 charges in front of judge Alex Ricciardulli — he denied the application.

Then the California Medical board attempted to restrict his licence in front of Commissioner Henry Hall who ruled that should Brown make bail he will not be allowed to treat female patients without a chaperone approved by the medical board.

The 37-year-old was originally arrested on July 8 after a year-long sex sting where an 18-year-old patient — and an undercover cop posing as a patient — alleged assault. He was bailed on $50,000 only to be arrested a second time in two weeks on July 21 when six new alleged victims came forward.

Eight of the 23 charges filed last month included sexual battery by fraud and are said to have happened while the patients were unconscious.

Ten counts were for sexual exploitation by a physician. Other charges include a lewd act against a 15-year-old female patient, an alleged rape and two charges of penetration by a foreign object.

Brown was then remanded on $4 million bail by Commissioner Hall, for fear he was a flight risk. Brown will now appear in court on September 9 for a preliminary hearing on all 33 charges.
