The City College stampede was a crowd crush event on December 28, 1991, in the City College of New York gymnasium during a charity basketball game organized and promoted by hip hop celebrities P. Diddy and Heavy D. Nearly 5,000 people tried to pack into the gymnasium, which could fit 2,730 people. Outside, people broke through at least one glass door leading to the gymnasium lobby. The crowd rushed the lobby and down a short staircase that led to the gymnasium. However, doors at the bottom of the stairs opened inward into the lobby, not outward into the gymnasium. The doors were left closed for up to 15 minutes as the crush worsened. Nine people were crushed to death at the bottom of the staircase, while 29 others were injured.
