A judge on Thursday sentenced Cathey to 10 years of probation and ordered him to serve six months in the Bell County Jail.
Cathey was arrested in September. An alleged prostitute told police she was pressured into having sex with a man, and not charge him, because he said he was an officer and threatened to have her arrested.
The Killeen Daily Herald reports that the 45-year-old Cathey, during police interrogation, said he used a badge with a circle and star emblem that reads "security officer."
