Undercover detectives from the Polk County Sheriff's Office kept their computers on Monday -- and caught another three men looking for sex with a child they met on the Internet.

The "child" turned out to be an undercover officer with Operation Guardian, the second online sting the Sheriff's Office has conducted this year.

But this time, instead of releasing the results and stopping their efforts, officers announced the 22 arrests from Thursday to Sunday and decided to keep going.

"We have no expectations," Polk County sheriff's spokeswoman Carrie Rodgers said. "We're doing this to see what impact the media coverage has, if any."
