Eric Munchel, 30, appeared before a federal judge, who ordered the Nashville resident held without bond pending further hearings, The Tennessean newspaper reported. Online sleuths accused Munchel, who was dubbed the "zip tie guy," of being one of two men who carried the restraints into the Capitol building on Jan. 6 amid a chaotic scene where supporters of President Trump engaged in a deadly riot.

Prosecutors asked that he remain in custody pending extradition to Washington D.C.

The FBI said photos of someone believed to be Munchel was carrying the restraints, an item in a holster on his right hip and a cellphone mounted to his chest with a camera facing outward. 

"In my experience, flex cuffs are used by law enforcement to restrain and/or detain subjects," FBI agent Carlos Fontanez wrote in an affidavit

Munchel has not been charged in connection with allegedly using the zip ties. 

When authorities encountered Munchel at a hotel in Washington D.C., on the day of the attack, they observed him carrying a "Taser Pulse," a taser that emits electrical shock, which he said he had for self-protection at the Trump rally that preceded the siege at the Capitol. 

Authorities said he attended the rally with a woman who was also pictured with him inside the Capitol, they said. Their relationship was not disclosed.

A hearing on Munchel's case is scheduled for Tuesday. 

"I want to remind you that it's very important that you communicate with them (attorneys) about your case. You need to speak openly and freely with them," U.S. Magistrate Judge Chip Frensley told him, according to the newspaper. "You don't talk to them and communicate with them, it's real hard for them to represent you. We have challenges in the COVID era, and they're going to work through those things, and I need to work with them so that they can do everything they can to represent you."
