FOLSOM, Pa. (CBS) – Three children are taken to the hospital following a scare on stage during a children’s play in Delaware County.

Authorities say a prop set on stage collapsed in the middle of the performance.

It happened around 9:30pm Friday at the Ridley Community Center in Folsom.

We’re told 15 to 20 additional children were hurt and evaluated at the scene. They are members of the Catholic Community Choir performing “Seussical” when it happened.

Authorities say all the injuries are minor and the cause of the collapse remains under investigation.
