NEW YORK (CBSNewYork) – The Queens Center Mall erupted into chaos Friday afternoon after police say a rapper’s book signing spiraled out of control. Authorities say Bronx-born rapper “A Boogie wit da Hoodie” – whose real name is Julius Dubose – was scheduled to appear inside the mall’s Puma store at 5:30 p.m. Video posted to social media showed people getting into fist fights and looting stores, as sheer chaos broke out around 2:30 p.m. “They grabbed the chairs and broke it on his head, the poor guy was bleeding,” witness Maria Moncada said. “It was bad.”
