Which Agency Holds a Report from Addison
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 Addison that is the agency that reports to the FBI for the city (filed by the FBI as Addison Police Department); outside it, the DuPage County Sheriff's Office.
The FBI's agency list also places two other agencies and two campus police departments in DuPage County, each with a records office of its own.
The Hanover Park Police Department, the St. Charles Police Department, the Bolingbrook Police Department and two more are each listed by the FBI across several counties including DuPage County, so their arrests are not broken out for DuPage County here.

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.
