Princeton University evacuated its campus on Tuesday, June 11, after receiving a bomb threat to multiple buildings on its sprawling New Jersey property, according to the school's Twitter page, Reuters reported.

Those with cars were told to leave the campus, and those without cars were directed by police to evacuation sites, the school said.

"This is NOT a test. There has been a bomb threat to multiple unspecified campus buildings," said one of the school's tweets at about 10:30 am (1430 GMT).

A spokesman for Governor Chris Christie said the governor was not in Princeton, which is home to the executive mansion, Drumthwacket.
