WASHINGTON (CNN) -- Capitol Police arrested a man Friday after an officer spotted a rifle in his car when he stopped the officer to ask for directions two blocks from the Capitol building. Police inspect the suspect's vehicle in Washington on Friday. Christopher Shelton Timmons, 27, has been charged with carrying a deadly weapon, having an unregistered firearm and having unregistered ammunition, Capitol Police spokeswoman Sgt. Kimberly Schneider said. In addition to the rifle -- an AK-47 -- police found a grenade, a pistol, ammunition, loaded magazines "and several other items of concern to the police" in the Jeep Cherokee he was driving. Authorities said Timmons was convicted of carrying a concealed weapon in March in Albemarle County, Virginia, and served a month in jail. In that incident, Timmons had two grenades in his car, said Albemarle Police Chief John Miller. The pins had been removed and the grenades were filled with powder, authorities said. They had an adhesive on top to close them and a firecracker for a fuse. Law enforcement sources said the grenades were similar to an item found in Timmons vehicle Friday. That device has been taken to the FBI facility in Quantico, Virginia. Members of the joint terrorism task force are involved in the investigation, sources said, but so far no one is suggesting Timmons was planning an attack of some kind.
