The Illinois Freedom of Information Act (FOIA) designates many records as publicly available. When making FOIA requests to the CPD, the request should be in written form, printed or typed, and must include the requester’s name, mailing address, daytime phone number, and a description of the records being requested. You can, if you wish, use the CPD Freedom of Information Request form offered on their website and, although it is not outright stated on their site, it will likely aid the process of fulfilling your request should you do so as the form is likely a part of their request fulfillment process and filing and probably will need to be filled out by staffers if a request arrives in an alternate form. There are four available ways in which to submit a FOIA request to the Chicago Police Department. It can be mailed to:

This office is open 8:30 a.m. to 3:30 p.m., Monday through Friday, excluding public holidays. The request can also be submitted by facsimile to (312) 745-6948. You will want to ensure that the cover sheet or document is clearly made to the attention of the “Freedom of Information Officer.”  Lastly, the request may be submitted by email to [email protected].
