A Broadway showing of To Kill A Mockingbird in New York City ended in chaos Wednesday after the crowd mistakingly mistook a motorcyle backfire outside for gunshots at the Shubert Theatre.

During the incident, fans started to flee the theater in a panic, causing a stampede. Footage from Times Square shows people running and screaming in fear, while other civilians were left confused and scared by the sudden rush of people. The actors on stage reportedly fled the scene as well, rushing alongside theatergoers to escape.

NYPD Midtown North confirmed that there was “no active shooter” in the area, and the sound actually came from motorcycles. Nonetheless, everyone was on edge, including actor Gideon Glick, who was starring in the show as Jeff Daniels. In a tweet following the gig, he said that the show was stopped and screaming civilians tried to leave the theater for safety, noting that “this is the world we live in. this cannot be our world.”

This gun scare isn’t something new; for years, people have been on edge due to gun violence in the country. A similar situation occurred in San Francisco during a showing of Hamilton earlier this year, causing the crowd to flee the theatre after gunshots in the play combined with an on-site medical emergency caused panic. Last year’s Global Citizen Festival ended in a frenzy when a bottle popped in the crowd, sounding like a gun shot, and Miami’s Rolling Loud Festival left fans scared when people believed they heard an active shooter.

Audiences have been fearful of attending live events due to these recent scares as well as very real shootings – like at the Gilroy Garlic Festival, Ariana Grande’s Manchester show, and the Route 91 Harvest Festival, which left 58 people dead and 489 people injured. Most recently, blink-182 had to cancel their show in El Paso after a gunman opened fire in a Walmart Supercenter, killing 20 people over the weekend. Many artists have been speaking out about the violence, calling for stricter gun control.
