Zone 1 is home to Northern Illinois University. Its nearly 17,000 students and 3,300 faculty and staff are served by the NIU Department of Public Safety, but DeKalb Police often work with the officers from NIU. Through a co-policing program, City and NIU officers attend each other’s roll calls and training sessions, patrol together and work collaboratively to enhance safety on campus and in the neighborhoods surrounding the university.
