GREEN BAY, Wis. (AP) — Law enforcement has arrested 16 men in six Wisconsin counties in a sting that targeted Internet child sex predators. Eight were arrested in Brown County, four in Marathon County, and the others in Winnebago, Shawano, Outagamie and Door counties. Door County Sheriff's investigator Jim Valley says police had between 1,200 and 1,500 chats with possible suspects during the investigation that ran from Wednesday to Saturday. Officials targeted online ad services as well as social media and other Internet outlets. By Monday evening, eight men had been charged. Charges — and those being recommended — include use of a computer to facilitate a child sex crime to child enticement, prostitution and possession of a controlled substance. Law enforcement officials say the investigation continues.
