The Illinois State Police are considering whether to get involved with an investigation into a hidden fund at Northern Illinois University. State police spokesman Sergeant Jose DeJesus says the agency's Internal Affairs division is currently reviewing the case of the so-called "coffee fund." University officials acknowledged they were looking into allegations that NIU employees sold scrap materials to a local company, which wrote checks to an account known as the ``coffee fund.'' Because the matter involves a public university, the case was turned over to the state for review. The department has not yet decided whether or not it will investigate the alleged misuse of funds. The NIU police department already is conducting an internal investigation into the coffee fund. The DeKalb County State's Attorney also is monitoring the situation.
