The Walton County Sheriff’s Office says an employee of the Walton Academy for Growth and Change, a residential facility for troubled juveniles, has been arrested for allowing a 15-year-old boy to be sexually assaulted by a group of delinquent teens. Investigators say     27-year-old Antoine Davis stood in the cell’s doorway, laughing as the group of four teenagers sodomized the 15-year-old with a shampoo bottle. The teen suspects were each charged with false imprisonment and lewd and lascivious battery. Davis is facing similar charges and well as an additional battery charge. He’s being held on a $100,000 bond. The Florida Department of Juvenile Justice said the incident is under investigation.
