Nov. 1 (UPI) — The FBI, local and university police are investigating an “intentional” explosion that occurred early Saturday morning on the fourth floor of the Harvard Medical School building in Boston.
The explosion occurred at 2:48 a.m. EDT in the medical school’s Goldenson Building and triggered a fire alarm that alerted university police, The New York Times reported.
A Harvard University Police officer responded to the building at 220 Longwood Ave. and saw two individuals running from it.
The officer tried to stop the individuals but could not and then found evidence of an explosion on the fourth floor, according to The Boston Globe.
The Boston Fire Department and its arson unit also responded to the alarm and determined the explosion likely was intentional.
Boston police searched the building for explosive devices but found none.
No one was injured during the incident, and the FBI is assisting with the investigation.
University police released video stills of the two suspects, who appear to be young, white males wearing light-colored masks while fleeing the building.
One wore a brown sweatshirt with a hood and what looked like “NYC” printed on the front, khaki pants and gray Crocs.
The other wore a dark hooded sweatshirt and dark plaid pajama pants, according to university police.
The university police released images of each suspect that were captured by surveillance cameras.
