Authorities arrested a 15 year old-boy and charged him with a felony after they say he called in a bomb threat at a building housing two alternative schools in Morehead City. In an unrelated case, vandals struck Broad Creek Middle School in Newport. They broke windows and windshields, discharged fire extinguishers and made a huge mess inside and out. Carteret County investigators spent the morning, going over the crime scene and collecting evidence. Students were sent home for the day.
