Are Arrest Records Public in Cook County

Arrest records in Cook County are generally considered public information under the Illinois Freedom of Information Act (FOIA), codified in 5 ILCS 140. This statute establishes the presumption that all government records are open to public inspection unless specifically exempted. However, access to arrest records is subject to certain limitations and exemptions as provided by law.

Pursuant to Illinois Compiled Statutes Chapter 20, § 2630/3, law enforcement agencies are required to maintain arrest records, which become part of the public record once an individual is arrested. It is important to note the distinction between arrest records and conviction records:

  • Arrest records document that an individual was taken into custody by law enforcement on suspicion of criminal activity
  • Conviction records indicate that an individual was found guilty of a criminal offense through the judicial process

The Illinois State Police maintains the central repository for criminal history record information in the state, including arrest data from Cook County. While arrest records are generally accessible, certain information may be redacted to protect privacy interests, ongoing investigations, or juvenile records.

Under 20 ILCS 2630/5, certain arrest records may be eligible for expungement or sealing, which restricts public access to these records under specific circumstances. Additionally, the Illinois Criminal Identification Act provides guidelines for the dissemination of criminal history record information.
