The suspects approached the victim, hitting him in the face with a weapon in hand while rummaging through his pockets and fleeing the scene with his property.
Police say officers found the two not long after a few blocks away, coming out of the Edward Everett Square Dunkin' Donuts.
Officers stopped the first juvenile and performed a pat frisk immediately recovering what appeared to be a firearm from his jacket. Recovered from the second juvenile was a large sum of cash, a gift card and a cell phone, all belonging to the victim.
The two were charged as being delinquent for armed robbery and assault and battery with a dangerous weapon, police say.
