An email warning claimed bombs were planted in four campus buildings as hundreds of students prepared to sit final exams.
In a statement on the university’s emergency web page, Harvard Executive Vice President Katie Lapp wrote: “I am relieved to report that no suspicious devices were found.
“I would like to thank the HUPD (Harvard University Police Department) and the many representatives of the local, state and federal agencies who responded to this incident. We deeply appreciate your help in keeping our campus safe.”
The Ivy League institution initially evacuated the four buildings after issuing a warning about “unconfirmed reports” of explosives.
The school, where final exams have begun, posted alerts on Twitter as police searched the Cambridge, Massachusetts, campus with bomb-sniffing dogs.
One student said she was preparing to start an exam when a fire alarm went off and everyone was ordered to leave the hall.
Freshman Hamidah Mahmud said: “We were about to take our science final in the Science Center. We had our pencils out, we were about to start it and right when he was about to say ‘go’ the fire alarm started and they evacuated everyone.
“Because the Boston bombings happened so recently, I think they are taking extra precautions.
“It was pretty scary.”
The Harvard Crimson newspaper reported that students were moved to Annenberg Hall, one of the college’s main eateries.
The paper said that Harvard dean of undergraduate education Jay Harris told those assembled in the hall that the morning’s final exams had been cancelled.
Transport police carried out a sweep of Harvard’s subway station, but it was not closed or evacuated, according to The Boston Globe.
Harvard’s main campus covers 209 acres in a heavily-populated area on the edge of Boston.
Last month, another Ivy League school, Yale University in Connecticut, was locked down for nearly six hours while authorities investigated a phone call saying an armed man was spotted on campus.
Authorities believe that warning was likely a hoax.
