Four Harvard buildings were evacuated after an explosives threat

A report of explosives sent to the Harvard University Police Department and others by e-mail shut down four buildings at Harvard today: Sever, Emerson, Thayer, and the Science Center. Final exams that were taking place in the affected classroom buildings were postponed, and the residents of Thayer Hall, a freshman dormitory in Harvard Yard, were temporarily evacuated. Harvard and Cambridge police were among the first responders, followed by Massachusetts State Police. All four buildings were eventually reopened shortly before 3 p.m.
