Students and staff of Louisiana State University are being urged by university officials to stay away from the campus until further notice.

University spokesman Ernie Ballard on Monday said the LSU sent another text to students at 1:36 p.m. CDT to remain off campus as the investigation continues.

"LSU continues to investigate the bomb threat reported earlier today. Please stay off campus unless directed to return," the text read.

A bomb threat was phoned into a local 911 after 10:30 a.m. CDT. The school has since evacuated the entire campus. LSU is home to approximately 29,000 students and 4,700 faculty and staff.

Last week, three other universities in different states received bomb threats but no explosives were found. Authorities are now reportedly looking into whether there is a connection.
