Internal Affairs Bureau
The mission of the Internal Affairs Bureau is:

  • To effectively and efficiently investigate allegations of misconduct by members of the Fresno Police Department;
  • To conduct all investigations in a fair and unbiased manner;
  • To provide a basis for appropriate administrative response.

California law requires every police agency to have a procedure for investigating citizen complaints, and to have a written description of the procedure available for review. The law also stipulates that these internal investigations, reports, and findings shall be retained for at least five years. Internal investigations are administrative investigations which are civil in nature, and not criminal. Criminal investigations differ in that they are designed to determine violations of law, administrative investigations deal with the question of compliance or noncompliance with Departmental rules, policies, and regulations. Citizens have a right to expect fair and impartial treatment from law enforcement personnel. Therefore, it is imperative that any police misconduct be reported and corrected as quickly as possible.

All complaints are initially reviewed by a supervisor. If the complaint cannot be resolved or the supervisor believes misconduct may have occurred, the complaint will be thoroughly investigated. The accused officer’s supervisor will typically handle the initial receipt of complaint by interviewing the complainant. Allegations of misconduct which are serious in nature, i.e., excessive force or criminal acts committed by a police department member, are usually investigated by the IA Bureau after the initial receipt of complaint is taken.

The Internal Affairs Bureau consists of a secretary, five investigator sergeants, and one lieutenant. Once a complaint has been forwarded to the IA Bureau, a thorough investigation is conducted. The IA sergeant will typically retrieve police reports, medical records, photographs, and other physical evidence if available. The sergeant will interview witnesses and the accused officer(s) and may also re-interview the complainant if needed. The sergeant will prepare a detailed administrative report which outlines his/her investigation. Staff officers in the accused officer’s chain of command then review the investigation report for completeness and thoroughness. If the investigation determines that employee misconduct occurred, the Chief of Police or designated staff officer will determine the appropriate discipline or corrective action. Police department employees may receive training or may be counseled, reprimanded, fined, suspended or terminated, depending on the degree of misconduct and the disciplinary history of the employee.

Once the investigation is completed, the police department will mail the complainant a letter advising them of the investigation’s findings. However, California State law prohibits disclosure of what discipline the employee received. If the investigation takes longer than thirty days to complete, the Department will notify the complainant of the status of the investigation, and keep them updated every thirty days thereafter until the completion of the case.
