A man wanted in connection with an alleged assault at a protest in Morristown Saturday night is in custody, authorities said.

Capt. Chad Mullins, with the Hamblen County Sheriff's Office, said 21-year-old William Cade Black was arrested around 10 a.m. in Arkansas. He said he had no other details about the arrest at this time.

Black had been wanted after he allegedly knocked a 21-year-old man unconscious during a protest at the Morristown City Center.

Police, including members of the Criminal Apprehension Unit, located Black Monday afternoon at the Bartlette Place office complex on West Morris Boulevard, but ended a  pursuit of Black’s gray BMW on West Andrew Johnson Highway because his reckless driving endangered the public and police, according to a police report.

Black faces charges of aggravated riot, assault, felony evading arrest, reckless endangerment and driving on a suspended license.

Mullins said deputies are en route to pick Black up and bring him to Hamblen County.
