Illinois Uniform Crime Reporting

NIBRS Reminder


A National Incident Based Reporting System (NIBRS) resource page is available to help agencies transition to NIBRS. Some of these resources come directly from the FBI, while others were developed internally during the I-UCR Program’s NIBRS implementation planning phase. This resource page, one of the buttons above, will include updates on NIBRS transition activities when there is helpful information to share. Access the page by clicking on the NIBRS Transition logo at the right-hand side of the page.

Finally, we have established a means for directly emailing the ISP NIBRS Transition Team. Simply click on the email address to the right:

Corrected FBI Guidance on Warrant Arrests:

Agency arrests individual on warrant from other jurisdiction, without any local charges: Agency should not report anything to NIBRS for this. The jurisdiction where the warrant originated will report the arrest (either as an arrest segment on a Group A incident report or arrest report as a 90z).

Agency arrests individual on local charges and that individual also has a warrant from another jurisdiction: Agency will report incident within their own jurisdiction. If the warrant from another jurisdiction is for a group A offense, they can either clear it exceptionally OR place a detainer on the individual, leave it alone, and then enter an arrest when they pick the person up. If the warrant from another jurisdiction is for a Group B offense, they must not report an arrest at this time. It will not be reported unless they also place a detainer on the individual and then may report an arrest at the time agency picks them up.
