DALLAS (AP) âÄî School district documents show employees at a Dallas high school staged cage fights among troubled students, making them settle their differences with bare-knuckled brawls in a steel utility cage inside a boys locker room. A 2008 report says the principal and other employees at South Oak Cliff High “knew of the practice, allowed it to go on for a time, and failed to report it.” The report say the cage fights happened between 2003 and 2005. The documents were obtained by The Dallas Morning News for a story in its Thursday editions. Former Principal Donald Moten denied the allegations, saying he had nothing to comment on because the fights never happened.
