Two men, Logan David Patterson, 18, and Dominick Frank Cardoza, 20, were arrested Tuesday for a weekend explosion at a Harvard Medical research lab.

They are charged with conspiracy to damage a federally funded building using fire or explosives.

Authorities said tips from the public helped identify the suspects after surveillance images were released.

The men reportedly filmed the explosion and shared it with friends, and so far, investigators see no evidence of a political motive, CNN has reported.

The incident comes amid ongoing discussions between Harvard and the White House regarding federal funding and lawsuits involving the university.
