A San Bernardino County Sheriff's deputy was arrested for having sexual relations with a female inmate.

Johnathan Miller, 27, was booked on suspicion of being an officer who engaged in “sexual activity” with a detainee, according to the department.

Oops (allegedly):

Deputies say that they started to look into Miller after “jail staff received information regarding inappropriate contact between a male deputy and a female inmate” at Glen Helen Rehabilitation Center.

Authorities served a search warrant at Miller's home and interviewed him.

Apparently they didn't like what they found or heard.

The deputy, who was put on paid administrative leave, posted $25,000 this morning.
