Kourtney Lashea Joe, of 2117 Second Ave., was seeking a confrontation with a 12-year-old girl who attends Southside Elementary, Richmond County schools spokesman Lou Svehla said.
Joe never got in contact with her target, Svehla said. She was arrested at the scene and charged with possession of a weapon in a school zone and making terroristic threats. Joe boarded the bus on Third Avenue at Bolt Drive.
It was not immediately clear whether she brandished the box cutter, but Svehla said no one was hurt in the incident. The bus driver called the Richmond County Sheriff's Office, which arrived first on the scene, followed shortly by school safety officers.
