A former DeKalb County detention officer was indicted Thursday in connection with allegations that he had sexual contact with an inmate.

Zel Tirrell Mitchell was accused of having sex with an inmate in exchange for food and contraband sometime between November 2012 and March 2013, prosecutors said.

The inmate said that he was not forced by Mitchell into the sex act, according to Channel 2 Action News.

In March 2013, following an internal investigation by the DeKalb County Sheriff’s Office, Mitchell was fired, authorities said.

A DeKalb grand jury on Thursday charged him with violation of oath and sexual assault by persons with supervisory or disciplinary authority.

In an original 2013 indictment, prosecutors also charged Mitchell with indecent exposure. That charge will be dropped, prosecutors said.
