Mesa, Arizona residents who want to report police conduct should use the City of Mesas official complaint process to ensure their concern is logged and reviewed. This guide explains who can file, the information to provide, how to submit a complaint, what to expect during review, and the appeal pathways. It also identifies the municipal office that handles investigations and where to find official forms and contact numbers. Use the steps below to prepare a clear complaint so the Professional Standards/Internal Affairs unit can investigate efficiently.

Overview

The City of Mesa handles allegations of officer misconduct through the Police Departments Professional Standards or Internal Affairs function. Complaints may be administrative (policy or conduct) rather than criminal; criminal allegations can be referred to prosecutors when appropriate. Complaints may be submitted by victims, witnesses, or third parties acting on behalf of a complainant.

Who can file

  • Victims directly affected by police action.
  • Witnesses who observed alleged misconduct.
  • Family members or authorized representatives for those unable to file.

How to submit a complaint

Common submission methods include online complaint forms, phone reports, mailing a written statement, or filing in person at a Police Department facility. Provide names, dates, locations, officer badge numbers (if known), and any evidence such as photos or video. For the official contact point and submission options, see the Mesa Police Department Professional Standards page Mesa Police Department - Professional Standards[1].

File as soon as possible to preserve evidence and witness memory.
