SAN DIEGO - More than 20 charges involving a dozen additional alleged victims were added Tuesday against a former dental assistant accused of sexually assaulting girls and women while they were under anesthesia in the dental office where he worked for three years.
Luis Ramos, 36, was originally arrested last month and charged with seven felony counts of sexual battery of an unconscious 17-year-old patient.
On Tuesday, Deputy District Attorney Martin Doyle added 24 counts, including felony sexual penetration and misdemeanor sexual battery.
Ramos had been out of custody on $100,000 bail, but was taken back to jail when Judge Dan Link increased the bail amount to $1 million, noting an "extreme change of circumstances."
Deputy Public Defender Mignon Hilts unsuccessfully argued that Ramos' bail be set at $500,000.
The defendant is accused of molesting 13 women, ages 17 to 62, from January 2015 through this January, and faces 18 years in prison if convicted.
"These charges involve Mr. Ramos taking advantage of his position as a dental technician to commit sexual acts on women who were anaesthetized," Doyle alleged outside court.
At the defendant's arraignment, Doyle said detectives were sifting through 500 hours of surveillance video from Park Boulevard Oral & Maxillofacial Surgery to see if they could find evidence of other females being molested.
A number of calls subsequently came into the San Diego Police Department, authorities said.
In the initial case, Doyle alleged that Ramos molested the girl -- touching her breasts and putting his face in her chest -- for about seven minutes while he was alone with the teen at the surgical office on Jan. 21.
Ramos had worked for the surgical office for three years, Doyle said.
A preliminary hearing is set for April 5.
