Two Massachusetts men were arrested in connection with an explosion Saturday at a Harvard University medical building.
The FBI Boston Field Office announced the arrests Tuesday morning in a post on X. Additional details will be shared at a press conference in the afternoon.
The explosion occurred shortly before 3 a.m. on the fourth floor of the Goldenson Building, part of the school’s medical campus in Boston. No injuries were reported.
Harvard police said officers saw two people flee the building after the fire alarm sounded. They were captured on security footage and their images were released to the public.

An initial assessment by the Boston Fire Department showed that the explosion “appeared to be intentional.”
