Email is accepted. The department has five business days to respond. Extensions of five more days are allowed with a written explanation. The first 50 pages of copies are free in black and white.

Naperville Police Blotter and DuPage County
Naperville is mainly in DuPage County, with a small section extending into Will County. For most police blotter records, DuPage County is the relevant county jurisdiction. When a criminal case starts with a Naperville arrest, the police blotter entry stays with the police department. Court records move to the DuPage County Circuit Court. Case filings, hearing records, plea agreements, and sentencing data are all at the county level. To track a case from the initial police blotter entry through to its conclusion, you may need records from both the city and the county.
The DuPage County Sheriff handles unincorporated areas near Naperville. If an incident happened just beyond the city limits, the sheriff's office may hold the record. The DuPage County jail processes bookings for people arrested in Naperville who face county charges. These booking records are available through the sheriff's office. Check the address of the incident to figure out whether the Naperville Police Department or the DuPage County Sheriff has jurisdiction.
Note: A small portion of Naperville extends into Will County, so some cases may go through the Will County court system instead.
Police Blotter Exemptions in Naperville
Most Naperville police blotter records are public. The exemptions under 5 ILCS 140/7 are narrow. Active investigations can be withheld if releasing the records would interfere with the case. Records that could endanger someone's safety may also be held back. Juvenile records have separate protections under Illinois law and are generally not included in the public police blotter.
If the Naperville Police Department denies your request, they must tell you which exemption they used. You can appeal. The Public Access Counselor at the Illinois Attorney General's office handles FOIA disputes at no cost. The process favors disclosure, so basic police blotter data like arrest names, charges, and incident types almost always comes through. A clear, specific request is the best way to avoid delays or partial denials.
