A year after two bombs hidden inside backpacks exploded at the Boston Marathon, police again were forced to evacuate the finish line area to investigate two suspicious backpacks, at least one of which was deposited by a man in a veil yelling "Boston strong."

According to Boston police, a man is now in custody in connection with the suspicious bags.

UPDATE 7:30 am: The man in custody has been identified as Kevin "Kayvon" Edson, a 25-year-old student at the Massachusetts College of Art and Design. Both backpacks contained rice cookers filled with confetti.

UPDATE 9:38 pm: Boston police and bomb squads have detonated both backpacks in controlled explosions. It's not yet clear what was inside them.
