Two Massachusetts men arrested after explosion at Harvard Medical School, says FBI

"On the day of the blast, surveillance footage captured the two walking toward Harvard's medical school. Witnesses said the pair chose the building because it looked abandoned and got into it through the roof, the charging document states. Witnesses said the pair lit a Roman candle firework outside of the building and placed a cherry bomb inside of a locker in the building that then exploded, according to the charging document."

"Anxiety levels naturally rise when the public learns that an explosion was intentionally caused, US attorney Leah B Foley said at a news conference, noting that the investigation is ongoing, but that there's no further threat to the university. Let me be clear: setting off an explosive device inside a locker at an institution geared toward higher education is not some harmless college prank. It's selfish, it's shortsighted, and it's a federal crime, said Ted Docks, the FBI's special agent in charge."

Two Massachusetts men were arrested and charged with conspiracy to damage by means of fire or an explosive after an early-Saturday explosion on the fourth floor of Harvard Medical School's Goldenson Building. The building houses neurobiology labs and offices. No injuries occurred and medical school officials reported no structural damage and intact labs and equipment. Witnesses reported the men had been visiting Wentworth College for Halloween activities, entered the Harvard building through the roof after choosing it for its abandoned appearance, lit a Roman candle outside, and placed a cherry bomb inside a locker that then exploded. The Boston Fire Department determined the blast was intentional and the investigation remains ongoing.
