Days after the Denver Police Department announced that it was investigating allegations that girls at a high school cheerleading camp had been forced into a painful splits position by their coach and teammates, the coach has been fired.

The allegations had caused five officials from Denver Public Schools to be placed on leave — including the coach, the principal and the assistant principal at East High School — the school system’s superintendent, Tom Boasberg, said in a statement on Wednesday. Mr. Boasberg announced Friday night that the coach, Ozell Williams, had been fired, and that an outside law firm had been hired to investigate.

“Under no circumstances should a young person be in a situation where they are suffering physical or emotional harm,” Mr. Boasberg said. “Under no circumstances should a young person be forced to continue any activity beyond the point they have expressed the desire to stop.”

The announcement came after a widely circulated video showed a 13-year-old girl, an incoming freshman, being forced into a split, with one leg in front of her and the other stretched behind her, even as she pleaded repeatedly to “please stop” and appeared to cry out in pain.
