A former Oklahoma Highway Patrolman charged with sexually assaulting three women during traffic stops is due in court.

Eric Roberts is due in Creek County District Court Thursday morning for a preliminary hearing on 11 criminal counts, including second-degree rape, indecent exposure, sexual battery and embezzlement.

The allegations came to light when a woman filed a federal lawsuit alleging Roberts raped her following a traffic stop. Two more women later made similar allegations.

Roberts has pleaded not guilty to all charges and is free on bond.

Roberts was suspended in July 2014 and resigned two months later following his arrest.

The head of the Oklahoma Highway Patrol has said Roberts turned off his dashboard camera during six traffic stops, including two referenced in the federal lawsuit.
