The evening performance of Broadways To Kill a Mockingbird came to an abrupt halt Tuesday when motorcycle backfire sounds outside the theater were mistaken for gunshots .

As Deadline first reported Tuesday , the incident took place shortly before 10 p.m. and during the final scene of the play, which stars Jeff Daniels and Celia Keenan-Bolger . When a motorcycle backfired near New Yorks Times Square, frightened pedestrians began dashing into the lobby of the Shubert Theatre, as well as Sardis restaurant, a popular nightspot for theatergoers located across the street.

According to Gideon Glick , who plays Dill Harris in the show, the sounds of the crowd emanating from both the theaters exterior and the lobby sparked panic among both the Mockingbird cast, who left the stage, and audience members.

Keenan-Bolger, who won a Tony Award for her portrayal of Scout Finch, shared her perspective on the terrifying experience in a series of tweets.

According to Playbill , the panic also reached the nearby Music Box and Imperial theaters, where the hit musicals Dear Evan Hansen and Aint Too ProudThe Life and Times of The Temptations are being staged.

While the performances of those shows had both concluded, cast members and audience members were asked to stay inside the theaters until the fracas outside subsided.

The New York City Police Department addressed the reports in a tweet late Tuesday, confirming that the sounds had, in fact, been motorcycles backfiring.

The incident came just days after a pair of mass shootings in El Paso, Texas , and Dayton, Ohio , left at least 31 people dead across the two cities.

A representative for To Kill a Mockingbird declined to comment.
