Virginia Tech police are investigating new threats of another mass shooting at the university in online YouTube postings.
Police say in an e-mail sent to faculty and students late Wednesday that at this time they don't believe the postings pose a danger to the school.
Authorities had investigated similar threats in October and believe the new posts are from the same person. Police say they are highly confident the posts originate from Italy.
Virginia Tech was the scene of the worst mass shooting in modern U.S. history in April 2007. Student Seung-Hui Cho killed 32 students and faculty members on campus, then took his own life.
Virginia State Police and the FBI are assisting in the investigation.
