ARAPAHO, Okla. -- An Oklahoma sheriff resigned after an investigation revealed he was running a sex-slave operation from his jail, police said.

Michael Burgess surrendered to Oklahoma State Bureau of Investigation agents and posted bond Wednesday night, hours after he resigned as Custer County sheriff amid 35 felony charges, including accusations of forcible oral sodomy, kidnapping, rape and perjury, KOCO-TV in Oklahoma City reported.

Investigators said that at one point, Burgess oversaw wet T-shirt contests at the Custer County Jail.

The 35 charges against Burgess include bribery of a public official, indecent exposure, 14 counts of second-degree rape and rape by instrumentation.

The Texas County district attorney started looking into Burgess in May 2007, after a participant in the Washita-Custer County drug court program told investigators that Burgess made her have sex with him on a threat of sending her to prison, the television station reported.

Because of a conflict of interest, Custer County prosecutors handed the case to Texas County authorities.

Burgess had been sheriff in Custer County since 1994. Residents said that if the accusations are true, it sends a bad message.

"That you can't really trust anybody no matter if they're in power because people in power abuse their power," said Kim Whiteshirt.

If convicted on all counts, Burgess could face a sentence of up to 467 years in prison. Authorities said Burgess is also involved in a lawsuit over accusations of inappropriate actions.

A source in Custer County also said that while it's likely the county's undersheriff would take over as sheriff, details of succession would probably be ironed out on Thursday.
