Westchester, Illinois, in Cook County, has about 16,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Westchester depends on where the incident happened. This guide names each agency, where its records page is and what the Illinois Freedom of Information Act requires of it.
This guide covers which agency, the city's records page, the sheriff's reports, what the law requires and common questions.

Which Agency Holds a Report from Westchester
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
Inside Westchester that is the agency that reports to the FBI for the city (filed by the FBI as Westchester Police Department); outside it, the Cook County Sheriff's Office.
The FBI's agency list also places 14 campus police departments and 15 other agencies in Cook County, each with a records office of its own.
The Elgin Police Department, the Buffalo Grove Police Department, the Deerfield Police Department and eight more are each listed by the FBI across several counties including Cook County, so their arrests are not broken out for Cook County here.

What the Illinois Freedom of Information Act Requires
Under the Illinois Freedom of Information Act the agency must answer a request within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
A defendant who has been charged gets the report through the case: the State's Attorney, (312) 603-1880, handles discovery for pending cases.
