The Collins Elementary School secretary accused of having sexual relations with a 15-year-old eighth-grade boy surrendered to Richmond County authorities shortly after 5 p.m. Wednesday.
On Tuesday, the Richmond County Sheriff's Office issued an arrest warrant for Tiffiny Robinson, 28, on one count of sexual assault and one count of enticing a child for indecent purposes.
Robinson arrived at the Richmond County jail on Walton Way with her attorney, Richard Allen, and two other people who refused to identify themselves.
When a reporter asked Allen for comment after Robinson was dropped off, he said: "The case will take its own course."
Patrick Clayton, the Richmond County school safety and security chief, said school safety officials and sheriff's deputies visited the home of Robinson and her "loved ones" to find her for an arrest.
"We've been actively pursuing her today," Clayton said earlier Wednesday afternoon. "We've issued a be-on-the-lookout (alert) for 911, and we've been actively looking for her all day long."
Clayton also confirmed that Robinson had been charged with shoplifting, a misdemeanor, in 2004.
Robinson, who has been placed on administrative leave while the school district's investigation into the allegations of sexual improprieties continues, has been secretary at Collins for five years.
She is also an assistant coach for the girls basketball and softball teams. Her salary in the 2009-10 school year was $19,115.
