A former Oklahoma Highway Patrolman accused of assaulting three women during traffic stops is due in court for his arraignment.

Eric Roberts is expected Tuesday morning in Creek County District Court, where he's facing numerous criminal counts related to three cases. The charges include second-degree rape, indecent exposure, sexual battery and embezzlement. Roberts has pleaded not guilty to all charges and is free on bond.

The investigation started after a woman filed a federal lawsuit alleging Roberts raped her following a traffic stop. Two more women later made similar allegations.

Roberts was suspended in July 2014 and resigned after his arrest.
