A man who stormed the Capitol in January has been arrested after he bragged about rioting while having his teeth checked at the dentist.

Daniel Warmus, 37, was arrested by the FBI after an anonymous person heard him bragging about his exploits in the Capitol riot and showing off pictures and videos from the day in the dentist, Daily Mail reports.

Agents were able to confirm that Warmus was present at the riot by tracing images from his passport photographs to footage taken on the day.

According to the FBI criminal complaint, the witness said he bragged about smoking marijuana in the building and defying a police officer's orders to leave.

The witness added that they saw Warmus in footage of the riot wearing a "Trump 2020" hat and a jumper with the phrase "CNN is fake news".

As he made his way around the Capitol building, he did so while holding a tree branch that had a large, dark-colored flag attached which read: "F**K ANTIFA" in white letters.

The Capitol building in Washington was stormed on January 6 by supporters of Donald Trump who sought to overturn the result of the 2020 election.

The incident left five people dead and more than 140 injured.

Warmus has now been charged with unlawful entry, disrupting government business, and disorderly conduct at the Capitol.

The 37-year-old made his first court appearance about the incident on Tuesday, May 18.

Cell phone records, as well as footage of the riots, confirmed that Warmus was present, the FBI has revealed, adding that the witness who overheard him bragging at the dentist refused to provide additional information after making the initial complaint.

Additional business records revealed that he is a registered agent for Worm-a-Fix Automotive, in Lancaster, New York.

News of Warmus' arrest comes after Donald Trump's niece Mary said that he enjoyed "every second" of the riots.

Per The Huffington Post, Mary Trump stated:

"He enjoyed every second of it. He is a physical coward but he’s perfectly happy when other people commit violence on his behalf.

"Secondly, again, he really thought that that was a way to change the results of the legitimate election."
