Fans of professional wrestling are familiar with staged brawls.

But on Saturday night, fans witnessed an impromptu, real-time melee at the Barclays Center when a spectator jumped into the ring and tackled 61-year-old wrestler, Bret (The Hitman) Hart, who was being inducted into the WWE Hall of Fame.

A brawl involving WWE superstars ensued. Some onlookers assumed it was just part of the show, a staged fight that is characteristic of WWE events, where reality and scripted narrative are often intertwined.

“It’s a wrestling show, so you don’t ever really know what’s going on when something like that happens,” Andrew Antillon, a spectator who was at the event, told CBS News.
