Sgt. John Barker of the Tuscaloosa County Sheriff's Office says an official at Lakeview Elementary School contacted authorities after the boy contacted authorities last week.
Barker says the child had several marks on his buttocks and upper thighs, and some of the BBs had broken his skin.
Sheriff Ted Sexton arrested 28-year-old Lewis Terrence Brown, Jr., Wednesday and charged him with torture and willful abuse of a child. He was released from the Tuscaloosa County Jail on $15,000 bail.
