USC investigates bomb threat, briefly shutting down parts of campus before area deemed safe

LOS ANGELES - An alleged bomb threat launched an hours-long investigation at USC on Sunday.

Prior to deeming the campus safe, the University of Southern California warned the public on social media around 2:45 p.m. on September 7 to stay away from Leavey and Doheny memorial libraries.

The school later said it wrapped up the search a little before 5 p.m.

As of Sunday night, it is unknown who left the fake threats.
