The hazing allegations at Maine West High School could result in criminal charges against the coaches.
Several student athletes have come forward alleging they were sexually assaulted by their teammates and that the coaches knew what was going on but turned a blind eye.
State law requires the coaches to report abuse, and Illinois' Department of Children and Family Services on Monday asked the Cook County State's Attorney's Office to look into whether any district employees broke the law.
The hazing incidents came to light last month when a mother said her freshman son was sexually assaulted in September during a hazing ritual by other members of the soccer team. Police reports obtained by the Chicago Sun-Times indicate that one coach watched one of the incidents and later congratulated the victim.
Six Maine West students have been charged as juveniles with battery and hazing while four other players have been disciplined by the school.
