POLK COUNTY, Fla. (WFLA) – A week-long undercover sting targeting human trafficking and online prostitution in Florida ended with 277 arrests.

“Operation No Tricks, No Treats” started last Tuesday, October 10 and ran through Monday, October 16.

During that time, undercover detectives posted fake ads or profiles online posing as prostitutes or someone who solicits prostitutes. Other detectives responded to profiles and ads posted by prostitutes.

Investigators say 215 suspects drove to Polk County from locations throughout Florida. Some were in the state visiting from Alabama, California, Delaware, Georgia, Louisiana, Michigan, Missouri, New Jersey, New York, North Carolina, Oregon, Tennessee, Texas and Virginia.

According to the sheriff’s office, 51 of the arrests were related to those who advertise as prostitutes online and 209 of the arrests were those who solicited undercover detectives posing as prostitutes. Seventeen arrests were made for other offenses.

“We are committed to fighting human trafficking by arresting those who engage in prostitution and trying to identify human trafficking victims,” Polk County Sheriff Grady Judd said in a news release. “It’s no secret…you need to stay out of Polk County if you’re going to commit crime.”

Polk County detectives worked with detectives and investigators from Haines City police, Lakeland police, Lakes Wales police and Winter Haven police.

Sheriff Grady Judd is expected to release more details about the undercover operation at a news conference Tuesday afternoon.
