Neal Pinkston, the Hamilton County district attorney general, released dashboard camera footage of the episode two days after it occurred, leading to outrage from African-American leaders, who described the search as a rape. The handcuffed man has not been publicly identified, and Mr. Brewer has not been charged with a crime.

Robin Flores, a lawyer for the handcuffed man, filed a lawsuit against the county, Mr. Wilkey and Mr. Brewer. He said in an interview that the long list of indictments against Mr. Wilkey was evidence of a “systemic” culture of abuse and cover-up in the county.

“It has been going on here for a long time,” said Mr. Flores, who has filed lawsuits on behalf of several people who claim they were abused by Mr. Wilkey and other deputies. “There is a pattern and practice of misconduct by the sheriff’s office and the county.”

“What we allege over and over again is that this sheriff has repeatedly softballed or slow-walked misconduct in the ranks and lays out this message to the troops that they can do what they want,” he added.

Several of the indictments filed on Tuesday relate to a different traffic stop, in February, that involved Shandle Riley, whom prosecutors say Mr. Wilkey stalked, assaulted, extorted and falsely imprisoned.

Ms. Riley, who is also a client of Mr. Flores’s, described the events of that night in a lawsuit filed in September against Mr. Wilkey; a second deputy, Jacob Goforth; and the Hamilton County government.

In it, she accused Mr. Wilkey of illegally searching her car — during which he found a small amount of marijuana — and then offering not to arrest her if she would allow him to baptize her.
