BORN: Sept. 11, 1992, in Denmark.
RAISED: In the Copenhagen area to Palestinian parents (now divorced) and a younger brother. Spent three years in Jordan.

NICKNAME: "Little Hussein from the Square," an ironic reference to his 6-foot, 2-inch (188-centimeter) height and Blaagaardsplads, a square in the Noerrebro district that was a hangout for a gang of immigrant boys who turned criminal, according to a source with knowledge of the criminal gang environment in Copenhagen.
GANG: Loosely connected to Blood and Brothers, the source said, speaking on condition of anonymity because he was not authorized to discuss ongoing police investigations.
