The FBI is assisting in a search for multiple masked suspects after an “intentional” explosion inside a building on Harvard University’s Longwood Medical School campus early Saturday.
Harvard officials told Fox News Digital that, just after 2:45 a.m., a Harvard University Police Department (HUPD) officer was dispatched to the Goldenson building at 220 Longwood Avenue in Boston for a fire alarm activation.
When the officer arrived, two people fled the building, officials said.

The officer tried to stop the pair before proceeding to the fourth floor, where the alarm was triggered, finding an explosion had occurred.
HUPD later released photos from surveillance footage of two people wearing masks and head coverings, seeking the public’s help in identifying them.
The Boston Fire Department Arson Unit responded and made an initial assessment that the explosion appeared to be intentional, officials said, and they believe a single device to be involved.
The Boston Police Department conducted a sweep of the building to check for any additional devices, and none were found.
