Someone in the stands took video of Coach Edward Douglas apparently targeting a player with expletives and more at last Thursday's game.
"For him to knock her hands down and push her face, was just, it was shocking, it was just, wow," said Michael Airhart, a spectator.
"You're trying to teach them how to be competitive and how to play but you're verbally abusing them and you're physically abusing them and it's wrong," said Andrew Holmes, a community activist and spectator.
The school's spokesman said the coach was fired Monday and released a statement saying in part: "We have met with the student, her parent, her teammates and their parents, and have communicated with all of our students and parents. The well-being of our students is our highest priority."
"I was heartbroken," parent Melloney Emanuel said. Her daughter doesn't play basketball at Christ the King, but Coach Douglas was her daughter's coach in elementary school. "He's a tough, tough coach. I think that's what these schools need now, a tough coach. A young, black coach who absolutely loved my kids."
ABC7's attempts to reach Coach Douglas were unsuccessful.
