Internal Affairs Unit

Arapahoe County is committed to providing the highest quality public safety services to our citizens. We value our relationship with our community members and all feedback assists us in evaluating the quality of the service we provide. 

Commendations and Complaints

We have an established system of commendation, complaint and disciplinary procedures. These procedures will not only subject the employee to disciplinary action when improper conduct is evident, but will also protect the employee when they properly perform their duties.

All complaints, including anonymous complaints will be accepted. If the investigation indicates misconduct, the employee will be disciplined according to the seriousness of the rules violation. 

The brochure below will clarify some rights you, as a citizen, have if you want to commend or make a legitimate complaint against an employee of the Sheriff's Office.


Commendations or complaints can be made by telephone, letter, email, or in person. They can also be filed 24-hours-a-day with the on-duty supervisor or during regular business hours with the Internal Affairs Unit.

Disciplinary Actions

Disciplinary actions can range from verbal counseling to suspension, or in extreme cases, termination. If the allegation is criminal in nature, the case will be presented for prosecution. 


In 2017, the Internal Affairs Unit completed 56 official internal affairs investigations in addition to a variety of other concerns and inquires. This unit also reviewed 651 Use of Force reports. By our policy, a review is required of all use of force incidents. Use of Force is defined as anything beyond compliant handcuffing. The unit reviewed 75 vehicle incident reports.
