CAMBRIDGE, Mass. (MyFoxBoston.com) – Harvard University was given the "all clear" Saturday after a man with an assault rifle, suspicious packages and bomb threats were reported.
At about 9:45 a.m., officers responded to the campus after 911 calls reported bomb threats at the university in four different locations. A caller also reported seeing a man carrying a rifle in the area, officials say.
"After extensive searches of all the buildings, clearing all the buildings floor by floor, room by room, everything turned up negative," Deputy Superintendent Joe Wilson said.
No bombs or an armed gunman were found. Police recovered what they believed was a suspicious package from a building on Prescott Street, but it was deemed not a threat.
Students and residents had to evacuate buildings including the Science Center and Harvard Yard. Several streets were blocked off due to the incident. One student said she is grateful that "we have the resources and the responders who are making sure we're safe in the event, this was real."
Cambridge police say they are working with the FBI to identify two people who claimed their responsibility on Twitter. FOX 25 found a tweet sent to a Boston reporter where the person appeared to be joking openly about the incident. The Twitter account was suspended soon after the exchange.
"It's very disturbing. A lot of resources went into clearing all of these buildings. Not to mention the inconvenience to everybody on a beautiful Saturday," Wilson said.
