The Office of Independent Monitor (OIM) accepts complaints and commendations for all civil service personnel, including police officers. All complaints are assigned a case number by the OIM and forwarded to the Internal Affairs Bureau of the Denver Police and / or Sheriff Department to be assigned to a sergeant for review. The OIM monitors the entire Internal Affairs process to ensure that it is handled in a reasonable and appropriate manner. For a more detailed description of the complaint handling process, visit the Independent Monitor's commendations and complaints page.
