Security was beefed up at Rockland Community College Friday following an emailed bomb threat that caused the campus to evacuate Thursday.

The bomb threat proved to be fake, but college officials say they aren't taking any chances. The email to the school's administration stated that there was a bomb planted in one of the buildings, and it gave a specific time for detonation.

School officials immediately ordered the campus to evacuate as the Rockland County Sheriff's Bomb Squad did a room-by-room search. Nothing was found, and the school reopened by late afternoon.

Classes resumed Friday morning, but the college's public safety force increased visible presence. Extra security officers as well as a bomb-sniffing dog were put in place for Yom Kippur services Friday evening at the school's arts center auditorium.

Students say the increased security is reassuring.

There's no word yet on how long the additional security will be in place. Police are working to trace that email back to its source.

Approximately 3,000 students attend classes at the college on a typical day.
