Authorities continue their search for two people in connection with an explosion at Harvard Medical School this weekend.

Catch up quick: Something exploded on the fourth floor hallway of the Goldenson Building in Boston just before 3am Saturday, CBS Boston reported.

No one was injured.
Harvard police said they saw two people running away as the fire alarm sounded.

What we know: The blast caused no structural damage to the building, and labs and equipment "remain intact," Harvard Medical School leaders wrote in a letter.

The Boston Fire Department said the blast "appeared to be intentional," the Harvard Crimson reported.

State of play: Harvard police increased patrols on the medical school campus on Monday, but said there was "no continued public safety threat."

Police ask anyone with information to call the Harvard University Police Department's detective bureau at (617) 495-1796.
