Three former Georgia prison inmates say state corrections officials didn't adequately protect them against sexual assault by a former high-ranking correctional officer.

The women allege in a lawsuit that former Department of Corrections Capt. Edgar Daniel Johnson used his position of power to intimidate and force them to engage in sexual acts with him while they were inmates at Emanuel Women's Facility in Swainsboro.

A lawyer for Johnson has previously said he denies the allegations. Lawyers for the state asked a judge last month to dismiss the lawsuit, which was filed in December but announced by the women's lawyers at a news conference Monday.

The women are seeking damages for alleged physical and mental suffering.

The Department of Corrections fired Johnson last year. He also faces criminal charges.
