What is OCI?

The Office of the Chief Investigator (OCI) serves as the investigative staff for the Detroit Board of Police Commissioners. The OCI directs the process of receiving and investigating citizens' complaints against the Detroit Police Department. The staff includes both civilian and sworn investigators.

How can I make a complaint?

If you have a concern regarding the performance of any Detroit Police Department employee, you have a right to file a complaint by letter, telephone, online, fax, or in person, through any entity of the Police Department, or in person at the OCI.


If you decide to speak with someone at the precinct, you will be referred to a supervisory officer. The supervisor will take the complaint detailing the allegations.

What happens next?

The citizen complaint report will be completed and forwarded to the OCI for further investigation. You will receive a copy of this report, and the Citizen Complaint Report Number. All complaints will be forwarded to the OCI for investigation and resolution. If your complaint alleges criminal conduct by an officer, it will be forwarded to Internal Affairs/Force Investigation.

The Chief Investigator, who is required by city charter to be a civilian, reviews all findings from the investigations and then makes a recommendation to the Board.

The findings are then reviewed and approved by a member of the Board of Police Commissioners. The findings are also reviewed by the Chief of Police or his or her designee. After approval by the BPC, the OCI will notify you in writing of the investigative findings.
