Capitol Police arrested a man Wednesday night after finding a shotgun and ammunition in his car.

Joshua Bowman, a 28-year-old from Falls Church, Va., attempted to enter the Capitol Police barricade at 1st and C Street Southeast, near the Capitol South Metro station, at about 8 p.m., just when President Barack Obama was beginning his speech to a joint session of Congress.

Bowman “approached officers and told them he wanted to park in the restricted area inside the barricade,— which is permit only, said Capitol Police spokeswoman Sgt. Kimberly Schneider. The barricades were in the up position, painted with a large red “STOP—, she added.

During a search of Bowman’s Honda Civic — to which he consented — officers spotted a gun case in his trunk. A further search turned up a shotgun and ammunition.

Bowman was arrested and charged with unregistered firearm and unregistered ammunition.

That’s the second such arrest this week. On Tuesday, a man entered the Hart Senate Office Building with a pistol and was arrested and charged with one felony and two misdemeanors.
