A 23-year-old Oregon man was arrested Wednesday morning after U.S. Capitol Police (USCP) officers found his tricycle-toting Subaru illegally parked on Capitol grounds with an alleged trove of weapons, including an antique sword, guns, knives and unregistered ammunition inside.

Nolan R. Churan is charged with unlawful activities, carrying a pistol without a license, carrying a rifle without a license, carrying a dangerous weapon — sword, possession of a high-capacity ammunition feeding device, possession of an unregistered firearm and possession of unregistered ammunition, according to authorities.

A rifle, handgun, bow and arrow, halberd axe, rapier sword, multiple rounds of ammunition, multiple knives, and a bow and arrow were allegedly found inside the Subaru, according to police.

“Our Threat Assessment Section is working to learn more about what Churan was doing on Capitol Grounds,” officials wrote in the release.
