Curtis Jiles, a 30-year-old teacher's aide at Tenoroc High School in Lakeland, Fla., is accused of paying or trying to pay students for sex both on and off campus, WTSP-TV reports.

Polk County Sherrif Grady Judd told the station authorities believe Jiles had sex with a student in a school bathroom and paid another to let him perform oral sex on the student in the back of a car.

According to the Orlando Sentinel, the four male students involved in the sex acts range from 15 to 17 years old.

Florida's ABC Action News reported Jiles had made arrangements to turn himself in following the issuance of an arrest warrant. But Jiles instead fired his lawyer and is now on the run, WTSP-TV reports.

"I've got news for Mr. Jiles," Polk County Sherrif Grady Judd told the station. "You're going to the Polk County Jail and there's going to be a whole lot of people looking for you ... because you're a real bad guy."

Jiles faces charges of sexual battery by a person in custodial authority, sexual activity with minors, and procuring a person younger than 18 for prostitution.
