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.

Officers with the USCP First Responders Unit were patrolling Capitol grounds at about 9 a.m., when they noticed a Subaru Outback with a large tricycle strapped to the roof, according to a news release.

The vehicle was parked in an area reserved for congressional staff along the 200 block of Pennsylvania Avenue, NW, and did not have the proper parking permit. 

Officers spotted what appeared to be a bow and arrow, a knife and an empty pistol holster inside the car.

USCP analysts pulled Churan’s driver’s license, which officers and the USCP Command Center used to track him down near the North Barricade of the Capitol building. 

During an interview, Churan allegedly told officers he had guns inside the car, according to the release.

The D.C. Metropolitan Police Department’s firearms detection K-9 verified there was either a gun or ammunition in the vehicle, prompting a search by the USCP Crime Scene Evidence Specialists.

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

As of Wednesday afternoon, authorities had not determined a connection to Congress.

Churan does not have an active file with USCP. 

USCP did not immediately respond to Fox News Digital’s request for comment.
