JUNCTION CITY, Kan. (AP) — The sheriff's department in Geary County says a two-day undercover operation resulted in 16 arrests of suspected prostitutes, pimps and their customers. The sting was prompted by recent reports of sex trafficking in the area using underage girls. Authorities said they did not encounter any instances of that crime in this week's operation. Sheriff's deputies, along with police officers from Junction City and Grandview Plaza, carried out the sting by contacting men and women who advertised on certain websites. The officers arranged "dates" at a Junction City hotel and made the arrests once all of the elements of the crime were met. Geary County Undersheriff Tony Wolf says that some of the suspects were local, but others traveled from Topeka, Wichita and Manhattan.
