Donald Grady, police chief at Northern Illinois University, has been suspended from his job and banned from the police department, following a statement from a state judge about an investigation into a police officer, The Chicago Tribune reported. The judge found that the Northern Illinois department withheld key evidence that could have cleared an officer accused of sexually assaulting a student. The evidence was interviews with students who said that the alleged victim told them the sex she had with the officer had been consensual. Grady on Friday referred questions to the university administration.
