SYCAMORE – A judge declined to dismiss a rape charge against a former Northern Illinois University police officer Friday, but jurors are going to hear how police initially withheld important information.

Judge Robbin Stuckert ruled last week that NIU police intentionally withheld witness statements favorable to Andrew Rifkin, a former NIU police officer accused of raping a college student off campus. Rifkin’s attorney asked Stuckert to dismiss the sexual assault charge against the 24-year-old Northbrook man.

State's Attorney Clay Campell said Monday that he had requested state police investigate NIU Police Chief Don Grady and the department over the mishandled evidence. NIU President John Peters asked state police to review and help with all of NIU police’s pending investigations as state police saw fit.
