VIROQUA, WI (Ben Caxton) — A social media threat against a local high school student has led to an investigation by the Viroqua Area Schools District and Viroqua Police. The threat was reported by the student’s parents to police prior to the start of classes Monday morning. A letter from school administration to parents said that no students were ever in danger from an actual threat. Police appear to have tracked the threat to someone in Appleton who is not a student at the school. While classes were held on a normal schedule the school did increase security on campus checking identities of people entering the grounds.
