UPDATE: The man at the center of an excessive force investigation against two Hamilton County deputies went before a judge in Marion County Monday on unrelated charges.

James Mitchell turned himself in on Saturday facing four charges. He's been released from the Marion County Jail after posting a $25,000 bond.

He turned himself in hours after he appeared at a press conference with the local chapter of the NAACP. Mitchell's attorney Robin Flores said he found out about Mitchell's outstanding warrants in Marion County on Friday.

"Sheriff Hammond contacted the Hamilton County attorney, who then contacted me and alerted me," said Flores.

Flores said that's when they set up a time for Mitchell to turn himself in. 

"I found out on Friday about these warrants and we were going to do a voluntary surrender, on Sunday at 2:00 p.m.," said Flores. 

The warrants stemmed from two separate incidents. 

In February, a Tennessee Highway Patrol trooper noticed the vehicle Mitchell was driving had a possible window tint violation. After a short chase, Mitchell took off on foot, and the trooper lost him during that chase. According to the report, the trooper found a stolen gun in the car. 

Warrants were issued for possession of stolen property, unlawful possession of a firearm by a felon, and evading arrest. 

The aggravated assault charge stems from a July 1 incident in South Pittsburg, according to court documents. Mitchell allegedly beat a woman with a bat or a pipe before fleeing in a black Chevy Malibu.

Flores said the victim saw the first press conference.

"Following that press conference we understand that she made a call to the sheriff's office here," Flores explained. "He's on TV, why isn't he in jail?"

Flores said a Marion County detective called him about Mitchell's surrender following Saturday's press conference.

"So we immediately right after we got done with that presser drove him right up here and turned him in immediately," said Flores. "We had already set up 2:00 Sunday, the detective called me, and he has a job to do. So I wasn't going to make it harder. You know my guy is cloaked with innocence so guilty persons don't do what we did." 

Mitchell appears in court again on Wednesday, July 24. He is required to wear an ankle monitor and have no contact with the alleged victim.
