A gathering of fans waiting for a popular rapper at Queens Center suddenly turned into pandemonium, with youths shoving, kicking and punching each other to the floor.
Police say they don't know exactly what triggered the chaos Friday afternoon at the Queens Center mall. The crowd was quickly dispersed and the rapper who goes by the name of "A Boogie wit da Hoodie" later announced on Instagram that the event would be rescheduled at a later date.
Some fans used their cell phones to capture the scene and post it on social media.
The rapper had planned to meet fans at a mall sneaker store in the Rego Park neighborhood.
