A 27-year-old man was arrested by Capitol Police at the corner of Second and Independence avenues Southeast at around 10:45 a.m. Friday after a rifle, pistol and improvised explosive device were discovered in his vehicle.

The driver, who police identified as Christopher Shelton Timmons and whose last known address was in Orange, Va., was charged with carrying a deadly weapon, an unregistered firearm and unregistered ammunition.

Timmons was arrested after he stopped a Capitol Police officer for directions and the officer noticed a rifle case in his Jeep Cherokee, according to Capitol Police spokeswoman Sgt. Kimberly Schneider.

Timmons was detained without incident, but streets in the area were closed until about 3:30 p.m.

Also found in the vehicle were ammunition, magazines with ammunition and “several other items of concern to the police,” Schneider reported.

The IED, which Schneider said “resembled a hand grenade,” was taken to an offsite facility for detonation.
