MGM Grand PanicTyson–Holyfield II
After Mike Tyson was disqualified against Evander Holyfield on 28 June 1997, panic broke out inside and around the MGM Grand. Reports describe a fight, a popping sound, and fear of gunfire causing crowds to run through the lobby and casino area, though police and MGM said no gunfire was confirmed.
Overview
What Happened
Core Findings
Panic Beyond the Ring
Contemporary reports place the panic after Tyson’s disqualification. Crowds inside the MGM Grand lobby and casino area began running after a fight and a reported popping sound led many to believe shots had been fired.
Police and hotel representatives were reported as saying there was no confirmed gunfire. The property response included partial shutdowns, security and police activity, and precautionary closure of nearby Las Vegas Boulevard frontage.
Injury reporting is not perfectly aligned. The most defensible summary from the available sources is that around 40 to 45 people were injured, mostly minor injuries, with one broken ankle specifically mentioned.
