GREENFIELD, Iowa (AP) — Police say they are investigating allegations of hazing involving the wrestling team at Nodaway Valley High School in Greenfield. KCCI-TV in Des Moines reports the city’s police chief confirmed the incident but declined to reveal details other than to say it involved several students. The school’s athletic director, David Huff, sent a letter to parents Friday saying the school is aware of a hazing incident on the wrestling team and that the school conducted its own investigation. He says disciplinary action is being taken and the school is taking action to prevent a similar incident in the future. In the letter, Huff says school officials were “disturbed by this incident.” Superintendent Casey Berlau declined to say if any students had been disciplined and declined further comment.
