Update: The police just called the all clear. According to a state trooper, the situation was "an unfounded but suspicious event." I'm not exactly sure what that means. Understandably, everyone's got to be a little touchy right now.
Police have descended upon Virginia Tech's Burruss Hall this morning. Fox News has just confirmed that there's a bomb threat inside the building. A state trooper is expected to hold a press conference in the next few minutes.
