CAMBRIDGE, Mass. (WHDH) -
Authorities searched for suspects whose hoax calls triggered the evacuation of several buildings at Harvard University and a futile search for an armed man and bombs on campus.
Cambridge police spokesman Jeremy Warnick says police received four calls reporting bombs planted on campus and a man carrying an assault rifle at the Ivy League school on Saturday at around 9:45 a.m.
"The fire department told us that there was a suspicious package in the backyard that had been called in the police department," said student Joanna Gouth.
Harvard University's police department said in a community advisory that it immediately ordered evacuation of buildings identified by the caller.
Teams including Cambridge Police, bomb detection dogs, MBTA Transit Police and Boston Police assisted in the search.
By 1:40 p.m., all locations were cleared and nothing was found. Students are back inside their dorms.
According to police, a suspicious package was found but it turned out to be a trash bag wrapped in bubble wrap.
Warnick says police will work with FBI agents to identify two people who claimed responsibility on Twitter.
Anyone who may have any information regarding this situation is urged to call the Boston Field Office of the FBI at (617) 742-5533 or Harvard University Police Department Criminal Investigation Division at (617) 495-1796. The Associated Press contributed to this report.
