The Chatham County Sheriff's Office arrested and fired one of its deputies for inappropriate sexual contact with an inmate.

Corporal Samuel Richardson was investigated by the Internal Affairs Unit after inmate Amanda Walker reported the contact to another deputy. 

Richardson has been charged with violation of Georgia law by committing the felony offense of sexual assault by a person with supervisory or disciplinary authority.

He was an employee of seven years and had been promoted to Corporal on July 11. 

The case and all evidence will be turned over to the District Attorney's Office.
