Authorities Investigate Intentional Explosion at Harvard Medical School

2025-11-02

The BareStory

An explosion occurred early Saturday, November 1, at the Goldenson Building on the Harvard Medical School campus in Boston. Authorities stated that no one was injured as a result of the blast, which triggered a fire alarm just before 3 a.m., according to university police. Both the Harvard University Police Department and the Boston Fire Department have said the explosion appears to have been an intentional act.

A university police officer responding to the alarm observed two individuals running from the building but was unable to stop them. Authorities have since released surveillance photos of two people with their faces covered, described as wearing sweatshirts, who are being sought in connection with the incident.

The Harvard University Police Department reported that the explosion occurred on the fourth floor. Following the incident, officers conducted a search of the building for other potential threats but confirmed that no additional devices were found. A witness reportedly told investigators they were awakened by a bang, followed by a second one about five minutes later.

The investigation is being led by the Harvard University Police Department, with assistance from local, state, and federal law enforcement agencies. An FBI spokesperson confirmed the agency was assisting at the scene but directed further inquiries to university police. Authorities have asked the public for help identifying the two individuals seen leaving the building.
