DeKALB – State and federal law enforcement officials offered few details Wednesday about why they spent the day searching Northern Illinois University’s police station.

FBI agents, joined by officials from the U.S. Department of Education’s Office of the Inspector General, and the U.S. Department of Housing and Urban Development’s Office of Inspector General, arrived about 8 a.m. and worked throughout the day. The inspectors general at federal agencies typically investigate alleged fraud or waste of agency funds or in agency programs.

FBI Chicago Media Coordinator Joan Hyde declined to comment on the search or the underlying investigation. Hyde said the FBI typically did not announce searches, but decided to issue a news release about this one around 8:15 a.m. Wednesday to avoid passers-by noticing the police presence and worrying about a large emergency.
