WINTER HAVEN, Fla. -

Nearly 100 suspects, including a 15-year-old girl and a California youth minister, were arrested on prostitution charges over a 4-day period as part of an undercover sting by Polk County Sheriff's Office.

PCSO held a news conference on Monday to discuss the undercover sting operation, which targeted online prostitution ads.

The 92 suspects were charged with offering to commit lewdness, among other charges, after responding to ads on BackPage.com posted by undercover detectives posing as prostitutes.

Among the arrested were a 15-year-old girl from Sanford who went to the undercover location to prostitute herself, according to deputies. The girl has been prostituting since since was 13 years old and was branded with a gang tattoo, according to Polk County Sheriff Grady Judd.

Samuel Yoon, 45, a youth minister from California who was in Orlando for a youth ministry conference, came to the undercover location to have sex with a girl he thought was 14 years old.

"This is a dangerous man," Judd said, calling Yoon a 'pedophile.' His church, the New Community Mission Church in San Leando, Calif., has been notified.

Another arrestee was 50-year-old Raymond Skwainski from Davenport, a vice president at Popular Community Bank.

Judd said he will now investigate BackPage.com for making money off prostitution.
