Doris Carolyn Onken, 21, is charged with two counts of Assault and Battery by a Mob Third Degree in the beating of a 16-year-old boy at the Treasure City nightclub last month.
She is the sixth person to be arrested in connection with the beating. Five of those charged are bouncers at the club.
The boy was taken into a back room at the club on November 10 and beat with a belt and threatened with a gun, according to Captain Michael Nunn with the Florence County Sheriff's Office.
After the bouncers eventually let him go, Nunn says, the teenager went to the hospital by a private car and was treated and released for his injuries.
The victims mother says her son used someone else's ID to get in the club, but says he didn't deserve to be beaten by the bouncers.
