COLUMBUS, Ohio – Students withholding information about an alleged rape in eastern Ohio last summer are thwarting investigators, school officials said Thursday, as the FBI looks into threats to local authorities who are working on the case against two high school football players.

The Steubenville school board also is expanding programs to raise further awareness of sexual harassment, bullying, date rape and substance abuse in the wake of the incident in August in which the two high school football players are accused of raping a 16-year-old girl.

The district said in a statement it is lining up training programs for faculty, staff, parents and students, with "targeted sessions" for student-athletes. The statement said officials were troubled to learn police were having difficulty getting cooperation from witnesses.
