Overview of the Incident
An explosion occurred early Saturday morning, November 1, 2025, at approximately 2:48 a.m. in the Goldenson Building of Harvard Medical School, located at 220 Longwood Avenue, Boston. The explosion, which took place on the fourth floor, was deemed intentional by investigators from the Boston Fire Department's arson unit. Fortunately, no injuries were reported, and the building sustained no structural damage, allowing it to remain operational.
Details of the Explosion
The incident was triggered by a fire alarm, prompting a response from the Harvard University Police Department (HUPD). Upon arrival, a police officer observed two unidentified individuals fleeing the scene. The officer attempted to stop them but was unsuccessful. Following this, the officer discovered evidence of an explosion in the hallway. A subsequent sweep of the building by the Boston Police Department found no additional explosive devices.
Ongoing Investigation
The investigation is being conducted collaboratively by the Harvard University Police, Boston Police, and the FBI. Authorities have released surveillance images of the two suspects, who were seen wearing masks and hooded sweatshirts. One suspect was described as wearing khaki pants and gray Crocs, while the other wore dark plaid pajama pants and a dark hooded sweatshirt. The police are urging anyone with information to contact the HUPD detective bureau.
Official Statements
Harvard officials reassured the community that there is no ongoing threat to public safety. In a statement, they emphasized, “First and foremost, we want to reiterate that thankfully no one was injured. The small section of the fourth-floor hallway where the explosion took place has been cleared and is fully operational.” The university has increased police presence on the Longwood campus to enhance security and comfort for students and staff.
Community Reactions
The explosion has left many students feeling unsettled. Some expressed concerns about their safety, with one anonymous PhD student stating, “We've all felt it, kind of like a target on Harvard's research back and this is where we do the most research.” Another student, Rakeem Yakubu, remarked on the shock of the incident, highlighting that the research conducted in the building is primarily for the public good.
Conclusion and Next Steps
As the investigation continues, authorities are focused on identifying the suspects and understanding the motive behind the explosion. The Goldenson Building is expected to remain open for classes, with cleaning crews ensuring that all areas are ready for the start of the work week. The community is encouraged to remain vigilant and report any information that could assist in the investigation.
