Special Agents from the Oklahoma State Bureau of Investigation arrested Kevin Buttler on complaints of 2nd degree rape after an inmate reported being sexually violated by the former detention officer.
OSBI began the investigation at the request of the Comanche County Sheriff's Office on July 25.
An inmate reported to jail staff that Buttler came into her cell the day before to deliver lunch. While in the cell, he unzipped his pants and motioned for her to perform a sex act on him.
She said the incident was brief after Buttler heard a noise and zipped up his pants. The inmate's cellmate was present at the time.
Buttler was questioned by OSBI on August 4. After the interview he was arrested and booked into the jail.
He is facing a 2nd degree rape charge.
