Most of Arlington Heights sits in Cook County. That means most arrests here send people to Cook County Jail. The Cook County Sheriff runs an inmate locator at cookcountyil.gov where you can search for anyone in custody. Type in the person's name and the system shows all matches. Each result lists the charges, booking date, bond amount, and where the person is housed at the facility.
Cook County Jail holds close to 5,750 people on any given day. It is the largest single-site jail in the country, located at 2700 S. California Avenue in Chicago.

Arlington Heights Police and Jail Records
The Arlington Heights Police Department is at 200 E. Sigwalt Street, Arlington Heights, IL 60005. You can reach them at (847) 368-5300. This is the agency that handles all law enforcement in the village. When officers make an arrest, the person goes through local booking at the police station before being transferred to the county jail.
Local booking includes fingerprints, photographs, and a log of the charges. This creates an arrest record that stays with the Arlington Heights Police Department. The person then moves to Cook County Jail where they go through a second intake process. Once that intake is done, the person appears on the jail roster and becomes searchable through the online tool. The whole transfer process can take several hours, so do not panic if you cannot find someone on the Arlington Heights jail roster right away after an arrest.
Arlington Heights Jail Roster vs State Prison
There is a key difference between the county jail roster and state prison records. Cook County Jail holds people on local charges. The Illinois Department of Corrections holds people sentenced to more than one year for felony convictions. These are two separate systems. If someone from Arlington Heights receives a state prison sentence, they leave Cook County Jail and go to an IDOC facility.
You can search IDOC records at idoc.illinois.gov. This is where the state keeps its inmate database.
Results from the IDOC search show the person's name, IDOC number, date of birth, current facility, admission date, and projected discharge date. The general public can also call IDOC at 217-558-2200 for help finding someone. Under 730 ILCS 5, the Unified Code of Corrections governs how inmate records are kept at the state level. The county jail roster and the IDOC database do not connect, so you may need to search both when looking for someone tied to an Arlington Heights case.
Public Records for Arlington Heights
Jail roster records for Arlington Heights arrests are public. The Illinois Freedom of Information Act, found at 5 ILCS 140, requires arrest reports to include the person's name, age, address, charges, time and place of arrest, and the arresting agency. If the person is held in jail, the report must also list when they were received, discharged, or transferred. Agencies have to provide these reports within 72 hours of the arrest.
For local arrest records, file a FOIA request with the Arlington Heights Police Department. For jail roster data from the county, send your request to the Cook County Sheriff's Office at 50 W. Washington Street, Chicago, IL 60602. The phone number there is (312) 603-6444. Some records may be withheld under Section 7 exemptions, such as those that could risk safety or compromise jail security. But the basic jail roster data with names, charges, and booking dates is available to anyone.
Note: FOIA requests can be submitted by mail, email, or in person at either the Arlington Heights police station or the Cook County Sheriff's Office.
