The FBI served a search warrant on the NIU police department this week. The actual subject of the investigation has not been publicly revealed, but I have read speculation that the search may related to last fall's indictments of several NIU employees who were conspiring to sell University-owned scrap metal off the books. Or not. It also may be related to the police chief who was fired last month. Or the NIU police officer who was indicted for rape last month. Or the NIU Vice President took a leave of absence today. Or something else entirely.
Anyway, in case anyone is interested, here is a copy of the federal search warrant that I obtained from the Justice Cafe twitter account (@facsmiley).
