BEREA, Ohio (AP) — Four high school football players near Cleveland have been charged with taking part in the sexual assault of several teammates.

Prosecutors say an investigation into the hazing during a summer camp found multiple victims.

Berea City School Superintendent Tracy Wheeler says the district isn’t releasing the names of the students or saying what discipline they might face.

The superintendent says none of the coaches from Berea-Midpark High School knew about what happened during the June camp at Case Western Reserve University.

Three of the players were charged in juvenile court. Cleveland.com reports that one 18-year-old is facing charges that include rape, sexual battery, unlawful restraint and hazing.

The school says its investigation found a number of students were involved as participants or witnesses.
