At least some of the 10 victims, ranging in age from 3 to 15, were sometimes restrained and incapacitated for people who paid for sexual contact, authorities alleged.

Police said seven people have been arrested so far, but more are expected in connection to an alleged child sex trafficking ring in Alabama.

At least 10 children, ages 3 to 15, were sexually abused in an underground bunker in Brent, Alabama, Bibb County Sheriff Jody Wade said.
