DURANT, Okla. (KXII) -- A former Oklahoma police chief accused of raping a mentally disabled man pleaded not guilty in front of a Bryan County judge on Tuesday.

An affidavit states Bryon Gordon took a 33-year-old man with down syndrome to a hotel room at Choctaw Casino in Durant and forced him to perform oral sex.

The victim told investigators this happened every time the two went gambling there.

Records show Gordon checked into the hotel twelve times between June and October of 2016.

The affidavit says the victim claimed Gordon also made him perform sexual acts at Gordon's home in Pauls Valley.

Gordon was arrested and charged with the crimes this January.

When we asked him about it then, Gordon said the allegations weren't true.

"Once the investigator hears what happened and turns it into the district attorney, I am certain they won't pursue the case because there is zero to that," Gordon told us by phone.

Gordon has been a law enforcement officer in Colbert, Boswell, Garvin County and Paoli in the past.

In 2005, prosecutors say he pulled a woman over and claimed to be a Grayson County narcotics officer, which wasn't true.

Records show he was put on probation for impersonating a public servant.
