Virginia Tech Police said they are investigating after dozens of people in the campus community received a threatening email message.
University police said in a statement Monday that the email "included a threat to campus safety." Police did not say what kind of threat was made.
Chief Kevin Foust said in a post on the school's website that other schools received similar threats on Monday. He did not identify those schools.
The website said the campus is open and operating under normal conditions, and classes are in session.
A Tech spokesman did not immediately return a message on Monday.
Police are asking anyone with information about the email to contact authorities.
