More than a dozen students were hurt in a terrifying stage collapse at an Indiana high school auditorium.

Video shows students screaming as the stage at Westfield High School collapsed while students danced during the final song of the “American Pie” musical.

Authorities say no one was critically injured in the ordeal.

Investigators will inspect the stage to determine what went wrong.

Superintendent Mark Keen said the orchestra pit has a cover that can be put in place so performers can get closer to the audience. He said the cover gave way almost immediately. Keen said they were looking at inspection records for the stage and were unclear exactly what caused the collapse.

Westfield Mayor Andy Cook said he was “most proud” of the effort from first responders after the stage collapsed between 10:08 p.m. and 10:10 p.m. Thursday. He spent much of the night visiting hospitals where the injured were taken.

“I was able to get back into the emergency room and talked to three young ladies,” Cook said. “All three of them, including the that was initially listed in critical, were in very good spirits. I was thrilled to see that.”
