“Several people in the audience began running toward the exits,” Scherr told CNN. “I personally thought I was about to hear gunshots.”

Scherr, who later posted a video from the incident on Facebookand Twitter, said the man went on to shout other things before security took him out. The show resumed 10 minutes later.

It is not possible to discern what the man was saying from the video, which shows audience members’ apparently concerned reactions.

Samit Verma, a journalist at Voice of America, was seated in the balcony on the right side of the theater with his wife when he heard the man shouting.

“I initially could not make out what the man was saying, but as more people exited the main theater I could clearly see him making a Hitler salute and yelling ‘Heil Hitler!’ ” Verma told CNN. “Everyone around me appeared quite shaken by the experience, and some people were in tears.”

Another audience member, Heather O’Hare, said everyone was shuffling and getting up to go to the restroom during the intermission when she heard the disturbance.

“People in the front orchestra seats started to turn and look up at the balcony, and someone started shouting back: ‘Go Home, Nazi!’ ” she said.

“We were kind (of) confused and numb about what actually was happening, but several audience members were palpably upset and decided to leave during the intermission break. The entire right half of the row in front of me was gone after Act One.”
