Cook County Quick Facts
Cook County Sheriff Arrest Records
The Cook County Sheriff's Office is the main law enforcement agency for unincorporated areas and the county jail system. Their office is at 50 W. Washington Street in Chicago. You can call them at (312) 603-6444 for general questions about recent arrests or case status. The sheriff also runs the Cook County Department of Corrections at 2700 S. California Avenue, which is one of the largest single-site jails in the country.
To find someone who was recently arrested and booked into Cook County Jail, use the Cook County Sheriff inmate locator. This tool lets you search by name and shows current inmates along with their charges, bond amounts, and booking dates. It updates throughout the day as new arrests come in. The jail processes thousands of bookings each month, so the database is large. Search by last name for the best results. If you know the booking number, that works too.
Note: The inmate locator only shows people currently in Cook County Jail custody, not those who have been released or transferred.
Cook County Circuit Clerk Records

Requesting Cook County Arrest Records
Under the Illinois Freedom of Information Act (5 ILCS 140), agencies must release basic arrest data within 72 hours of an arrest.

For records from the Cook County State's Attorney's Office, send your FOIA request to their office at 500 Richard J. Daley Center in Chicago. Email them at SAO.FOIA@cookcountysao.org or use their online FOIA portal. The first 50 pages of black and white copies are free under state law. Additional pages cost up to 15 cents each. Agencies have five business days to respond, with a possible five-day extension.
The Cook County FOIA portal shown here is where you submit formal record requests to the State's Attorney office.
You can also contact the Chicago Police Department directly for arrests made by city officers at (312) 745-5308.
Recent Arrests in Chicago
Chicago is the county seat and by far the largest city in Cook County. The Chicago Police Department has its own adult arrest search tool where you can look up people arrested and charged as adults. This search shows names, charges, and arrest dates. Juvenile arrest records are not included. The tool updates with new data as arrests are processed.
If you want a full arrest history from Chicago PD, you can request a RAP sheet (Record of Arrests and Prosecutions). Go in person to Chicago Police Headquarters at 3510 S. Michigan Avenue. Walk-in hours are Tuesday through Thursday, 8:30 a.m. to 1:30 p.m. The fee is $16 and includes a free Illinois State Police criminal history transcript. Bring a valid state ID. Results arrive by mail in 7 to 10 business days. You can also send the request by mail with a money order and your fingerprint card.
Note: Chicago PD warns that if you have an active arrest warrant, police can arrest you at the station when you go to get records.
Cook County Statewide Databases
Several state-level tools cover Cook County arrests. The Illinois State Police runs the CHIRP portal for name-based criminal history checks. This shows conviction records from across Illinois, including Cook County. A name-based search costs $10 for electronic results. You do not need the person's consent for a name check. Under the Uniform Conviction Information Act (20 ILCS 2635), only conviction data is available to the public through this system.
The Illinois Department of Corrections inmate search shows people serving state prison sentences. This covers Cook County cases where someone was sentenced to IDOC custody. Search by last name or IDOC number. Pre-trial detainees held at Cook County Jail will not show up here since they are still in county custody. For those, use the sheriff's inmate locator instead.
Illinois VINE at vinelink.vineapps.com is a free victim notification service. You can register to get alerts when an offender's custody status changes in Cook County. The service runs 24 hours a day and is confidential. It tracks people in both county and state custody.
Cook County Court System and Arrests
Cook County has one of the busiest court systems in the nation. The Illinois Courts website provides general info about the court structure. Criminal cases from recent arrests go through the Cook County Circuit Court. The court handles felonies, misdemeanors, and traffic offenses. Each case gets a number when the state's attorney files charges.
After an arrest in Cook County, the process starts with a bond hearing. Most people see a judge within 24 to 48 hours. The judge sets bail based on the charges and flight risk. Court records from that point forward are public. You can track the case through the circuit clerk's online portal. Felony cases go to the Criminal Courts Building at 2650 S. California Avenue in Chicago. Misdemeanor cases may be heard at one of several suburban courthouses spread across Cook County.
Arrest records that lead to charges become part of the court file. If charges are dropped or the person is found not guilty, those records may later be eligible for expungement or sealing under the Criminal Identification Act (20 ILCS 2630). But while a case is active, the records stay public and searchable.
