DALLAS (Reuters) - A Texas teenager was arrested for placing a threat on social media to launch a mass shooting at a Dallas-area high school on Wednesday, officials said. The teen, who has not been identified, was arrested on Wednesday for making a "terroristic threat," after posting on Burnbook, an application to anonymously share messages and pictures online, to launch an attack on Dallas-area Princeton High School, police said. Students at the school were required to pass through metal detectors and have their bags searched before entering the building, school officials said.
