The report said that Phoenix police Officer Eric Amato and Greg Kauffman, a supervisor at an Ajo ambulance service, were directly involved in the December fight along Whiskey Row.
Investigators say former Prescott Valley police Chief Bill Fessler and former Yavapai County sheriff's Sgt. Bill Suttle lied to police who responded to the scene.
The report also recommends a charge of disorderly conduct against an alleged victim, Justin Stafford.
The Maricopa County Attorney's Office will decide whether any charges are warranted.
Suttle and Capt. Marc Schmidt submitted their resignations in March. Suttle is a former commander of a drug trafficking task force, while Schmidt was a member of the executive staff of the Sheriff's Office.
Yavapai County Sheriff Scott Mascher released this statement on Thursday:
"I have thoroughly reviewed the reports submitted by Coconino County Sheriff's officials regarding the Whiskey Row incident that occurred in Prescott on December 22, 2012. I want to assure the public we serve that the dedicated men and women of this office hold themselves to a higher standard. As your sheriff, I want to apologize to our community for any trust we may have lost as a result of this event. I know the badge has been tarnished and we will work relentlessly to regain the community's full trust and confidence."
