The inmate, Daryl Wallace, alleged Campbell “viciously beat” him — using his handcuffs like brass knuckles — in a Sept. 28, 2015, jail fight caught on video.
An internal sheriff’s investigation after the fight found Campbell broke departmental policy when he punched Wallace, and Campbell was suspended for 10 days. Records show the sheriff’s office referred the matter to city and county prosecutors, who declined to press charges.

Montgomery County settled the lawsuit with Wallace in 2017.
In Tuesday’s settlement, Campbell also agrees to accept a resignation from the department dated May 23, 2017. He and the union also agree not to make disparaging remarks or critical statements either verbally or in writing about the county or sheriff’s office.
Campbell did not return calls and messages Tuesday seeking comment for this story.
