Capitol police say they arrested an armed 80-year-old man who told investigators he wanted to 'deliver documents' to the Supreme Court

• US Capitol Police arrested an armed 80-year-old Georgia man on Capitol grounds Wednesday.
• Two others were detained but not taken into custody.

The United States Capitol Police arrested an armed 80-year-old Georgia man "illegally parked" in a "suspicious vehicle" outside of the Supreme Court building on Wednesday.

Two other individuals were detained, but not arrested, according to a USCP statement. The individuals said "they were here to deliver documents to the U.S. Supreme Court," the statement adds.

Authorities temporarily closed the roads surrounding the Supreme Court and the Library of Congress around 3:45 p.m. to investigate the vehicle, which was a white van, authorities said in the statement.

"The driver told us he had guns in the van. A K-9 also 'hit' on the vehicle," Capitol police said in the statement.

The authorities found two handguns and a shotgun inside of the vehicle.

USCP said in a tweet that they charged the suspect, who was not publicly identified, on three counts, including possession of an unregistered firearm, unregistered ammunition, and carrying a pistol without a license.
