Tyler Bradley Dykes, 25, of Bluffton, South Carolina, was arrested in Charlottesville, Virginia, and made his initial court appearance on Monday, according to court records. A federal judge ordered Dykes held in custody until a detention hearing on Wednesday.

Videos captured Dykes tearing down police barriers, attacking officers outside the Capitol and stealing a riot shield during a mob’s attack on Jan. 6, 2021, an FBI affidavit says.

In May, Dykes pleaded guilty to a state felony charge of burning an object with the intent to intimidate and was sentenced to 5 years in prison, with 4 1/2 years suspended. He was given credit for time he served in South Carolina while awaiting extradition to Virginia and finished serving his state sentence on Monday.

An FBI task force officer met and interviewed Dykes around January 2019 “regarding his potential ties to domestic extremist groups,” the officer wrote in an affidavit for the Jan. 6 case. Dykes may still have ties to extremist groups such as the South Carolina-based “Southern Sons Active Club,” the federal agent said.

Active clubs are a network of white supremacists who “see themselves as fighters training for an ongoing war against a system that they claim is deliberately plotting against the white race,” according to the Anti-Defamation League. In December 2021, the FBI received a tip from somebody who said Dykes had boasted about attacking officers at the Capitol. The tipster told the FBI that Dykes said he went there for “fun” and wanted to “make a statement.”

Dykes was wearing a gray gaitor over his face as he marched to the Capitol with two other people. Video shows him joining other rioters in tearing down barriers and attacking police officers on the east side of the Capitol, the FBI affidavit says.

The charges against Dykes include interfering with police during a civil disorder. An attorney from the federal public defender’s office was assigned to represent Dykes at his initial court appearance in Roanoke. That lawyer said he can’t comment on the charges.
