The Door County Sheriff’s Office says a 17-year-old student has been arrested for making a threat against Gibraltar School in Fish creek. Television station W-B-A-Y reports that investigators were notified about the threat at around 7:46 A-M Thursday, which had been posted on the social media app Snapchat the Wednesday night. Gibraltar school officials had diverted school buses that had not yet arrived at the building and placed the building on lock down. Deputies arrested a 17-year-old student at his home. The school re-opened after the student was taken into custody. The Sheriff’s Office says the student is facing charges of making terrorist threats.
