Police are now working to find the person who made the threat.

"We receive these kinds of threats on occasion. We take everyone seriously. So out of an abundance of caution we will always respond. We will always do the due diligence. In a case like this we need to get additional support from other law enforcement agencies to make sure that the building was absolutely safe when we opened up at 6 o'clock," Virginia Tech spokesperson Mark Owczarski said.
