Louisiana State University's main campus is being evacuated following a bomb threat.
LSU police said Monday on their website that they are investigating the threat at the Baton Rouge campus. Students and others were asked to evacuate "as calmly and quickly as possible."
Police did not provide details. There are 30,000 students, professors and university employees located on the campus.
Capt. Doug Cain of the Louisiana State Police says state police bomb technicians are on the scene. Cain says police are talking to their counterparts in states where university bomb threats were reported last week to determine whether there are similarities.
Campuses in Texas, North Dakota and Ohio were evacuated Friday after receiving bomb threats, but police found no explosives.
No specific location for the LSU has been identified and parish 911 had been called, the school said in a press release.
Classes at the school have been canceled, the Houston Chronicle reports.
"I was in the middle of taking a test and they walked in and told us we had to leave campus," Andrew Arceneaux, an LSU student, told The Advocate.
Around 30,000 students and faculty attend LSU.
Traffic getting out of the campus is in a gridlock, as students are sitting in buses at a standstill, The Advocate reports.
LSU System President William Jenkins told the newspaper that he readied the school's emergency response systems after learning about the bomb threat.
"We hope it's a hoax, but we can't take that chance," he said.
