Princeton Bomb Threat Prompts Campus Evacuation (UPDATE)

UPDATE: 6:43 p.m. -- After an extensive eight-hour search of the campus, Princeton announced at 6:25 p.m. that it was reopening the university.

Princeton evacuated campus due to a phone call "from someone who said multiple bombs were placed throughout campus at unspecified locations," the university said in a statement. No devices were found and university operations have returned to normal.

Original story: Princeton University evacuated its campus Tuesday morning in response to a bomb threat to "multiple unspecified" buildings, the school announced in an emergency bulletin.

All employees were directed to leave university offices at the Princeton, N.J., campus and were told, "Do not return to campus for any reason."

According to a tweet from the university, those without a vehicle to leave campus are being directed to an evacuation site by Princeton police.

Princeton said just after noon that it does not expect employees to return to work on Tuesday as it investigates the bomb threat.

"The University's Department of Public Safety is investigating the threat with local, state and federal law enforcement agencies," an update on the website said.

The spring semester has already concluded and commencement was held last week. Princeton spokesman Dan Day told WNBC there are some summer programs on campus.

The FBI is not participating at this time in the Princeton investigation, a representative told The Huffington Post, but cautioned "that can change at anytime."

Students who need a place to go are being directed to the Nassau Inn, Princeton Public Library and Princeton Arts Council building downtown.

A university update on Tuesday afternoon announced that authorities are currently inspecting buildings on Princeton's campus using bomb-sniffing dogs, and the search of campus facilities is expected to take several hours.

A bomb threat was also made on Tuesday near the Georgia State Capitol in Atlanta, USA Today reports.
