Paul Patrick Serdula, 47, was arrested Monday night on child molestation and sodomy charges, Cobb County police Sgt. Dana Pierce said.
Pierce said the investigation into Serdula is "far from over," and more charges are likely as additional victims come forward.
"We have victims, probably, in the early double-digits, and we expect as many as 100," he said.
Serdula was arrested for the second time in less than a week about 10 p.m. Monday at a local Holiday Inn Express. The new charges include aggravated child molestation and aggravated sexual battery stemming from an alleged incident on July 29, and aggravated sodomy allegedly committed on Sept. 16, according to jail records.
Pierce said the new charges "will probably keep him in jail without bond."
Serdula was initially arrested Nov. 18 on three counts of unlawful surveillance of patients at a Cobb County dental office. was arrested for the unlawful surveillance and eavesdropping of patients on Wednesday. Police officials said he did not work directly for any dental or medical physician.
Electronic recording devices and hundreds of videos were seized by investigators during an earlier search of Serdula's home, Pierce said.
"We are looking at tapes not only from the incident that occurred at the dental office, but also other incidents that are recorded that we are trying to find the location of that criminal activity as well as identify the victims," Pierce said.
Officials said the videos showed inappropriate criminal conduct against people who were under anesthesia at various medical or dental offices.
Pierce said anyone who thinks they might be a victim should first contact their physician or dentist, "find out if in fact Serdula was the one who administered anesthesia to them, and if that is the case, at that point, contact us and we will begin to investigate."
