CHARLOTTE, N.C. -- The middle school math teacher accused of sexually assaulting a minor is now facing additional charges.
According to Charlotte-Mecklenburg Police, detectives were notified by CMS Police regarding an investigation concerning a sexual assault case involving 26-year-old Charles Naas, a teacher who worked at Alexander Graham Middle School, and a student.
CMPD says the inappropriate sexual contact was made when the student went to Naas' home for tutoring. Additional information led detectives to sign warrants for Naas' arrest. The alleged incidents took place while Naas was employed as a math teacher at Alexander Graham Middle School.
One of Naas' neighbors said he couldn't believe the news.
"Holy moly," said neighbor Darrell Meadows, who said he has known Naas since he was a child.
Naas was charged with felony indecent liberties with a student by a teacher and sex act with a student. On August 18, detectives announced that Naas was charged with six counts of third-degree sexual exploitation of a minor.
"He didn't seem like the type who would do anything like that," Meadows said.
CMPD says investigators are working to determine if there are additional victims. Anyone with information on Naas or this incident is asked to call 704-334-1600.
