A bomb threat was called in to the TJHSST phone mail last night. We retrieved the message this morning. We called police and school security, and I requested that police use bomb-sniffing dogs to clear the building, which required evacuation of the building. We evacuated students and staff to the stadium and called for school buses to serve as warming stations for students who need them. FCPS security and Fairfax County police are on the scene. As soon as police cleared the building, students and staff returned to the building and the school day resumed.
