FBI agents removed boxes of files and what looked to be computer equipment in a raid at the Detroit Public Library Tuesday, The Detroit News reported. Nine FBI officials arrived with search warrants around 8 a.m. at the library’s main offices. They left shortly after 11 a.m. with boxes of financial records, the News said. The investigation was mainly conducted in Tim Cromer’s office. Cromer, the library’s chief administrative officer, has been at the center of recent spending controversies, and the FBI also searched his home in a separate raid Tuesday, a source told the News. Facing an estimated $10 million budget deficit, the library has had its share of troubles recently. Last year, the library system cut 20 percent of its staff and closed two of its 23 branches, according to the Detroit Free Press.
