ATLANTA (AP) — An Atlanta-area sheriff is facing an additional charge in a federal prosecution accusing him of violating the civil rights of people in his agency’s custody by ordering that they be strapped into a restraint chair without justification and as punishment.

A federal grand jury in April indicted Clayton County Sheriff Victor Hill, finding that he had violated the civil rights of four people at the jail.

The indictment says the men suffered pain and bodily injury when they were held for hours in a restraint chair even though they had complied with deputies and posed no threat.

A new indictment filed last Thursday adds an additional alleged victim.
