A 29-year-old man from Colombia was arrested Friday following a child-sex-crimes investigation involving the Wisconsin Dells and Lake Delton police departments. Joan Manuel Calderon Triana was taken into custody on allegations including sex with a child over age 16, child enticement, sexual exploitation of a child and representations depicting nudity, according to police. Investigators carried out a search warrant at a home in the village of Lake Delton as part of the case. Police said the investigation extends into both Adams and Sauk counties. Calderon Triana was booked into the Adams County Jail. The investigation is continuing, and the allegations have not been resolved in court.
