Rapper A Boogie NYC Mall appearance sparks crowd Riot and Looting.

Cops were called to the Queens Center Mall Friday after rapper A Boogie appearance led to an unruly crowd that some described as a stampede.

The “Drowning” rap-star was set to show up at the Puma store on the third floor, drawing a large crowd that apparently got out of hand.

Authorities say people were pushing, fighting, screaming and running. The event was canceled as a result.
