During the five-day operation earlier this month, the men communicated with undercover officers posing as young teens, and then traveled in hopes of having sex with them, police said.

Fifteen men — most of them from Gainesville — have been charged as part of an undercover sting targeting those who traveled in hopes of having sex with underage teenagers, police announced Tuesday.

Three of the men are University of Florida students — Quinton Reddick, 21; Siddhartha Jain, 27; and Hongyan Huang, 22. UF spokesman John Hines said the three are no longer allowed on campus and could be arrested for trespassing by UF police if they return. They may face additional action by UF.

The sting, called Operation Resilient, included some 46 law enforcement officers from six agencies, including the Gainesville Police Department, Alachua Police Department, Alachua County Sheriff’s Office, Cocoa Police Department, the Federal Bureau of Investigation, the Florida Department of Law Enforcement and the Jacksonville Sheriff’s Office.

During the five-day operation earlier this month, the men communicated with undercover officers posing as young teens, and then traveled in hopes of having sex with the people they thought were underage, police said.

Those arrested in addition to Reddick, Jain and Huang were: Ray Steven Wood, 43, of Ocala; German Daniel Varela, 36, of Gainesville; Cristian Omar Torres-Vega, 22, of Maxville; Toddrick Lavonne Speights, 20, of Gainesville; Zachery Reid Page, 22, of Gainesville; Darren Gene Lunbery, 47, of Williston; Scott Terry Kravatz, 38, of Gainesville; Edwin Cantero Hernandez, 56, of Spring Hill; Joshua Tyler Gillen, 25, of Keystone Heights; Jackie Lamar Bush, 24, of Gainesville; Jack Bergstresser, 59, of Lake City, and Doe Doe, 39, of Jacksonville.

Most of the men were charged with traveling to meet a minor for unlawful sexual contact, unlawful use of a two-way communications device or soliciting a child for sex, records showed.

During the sting, officers made contact with the men using the internet, posing as a 13- or 14-year-old boy or girl, or sometimes the child's guardian. During police interviews, some of the men said they had other reasons for traveling or that they had no plans to have sex with anyone who wasn't 18 or older, records show.
