WASHINGTON (CNN) -- Police blew up suspicious packages in a car parked near the U.S. Capitol on Friday, more than two hours after the two occupants told authorities the vehicle contained a bomb.The U.S. Department of Labor building, less than two blocks away, was shut down, CNN's Ed Henry said. That building is at the corner of Third and Constitution. The vehicle is parked in the 100 block of First Street N.W.No evacuations were ordered for the Capitol, about another two blocks away. But some streets in the area were blocked off, amid heavy police presence.Police interviewed the car's occupants, both white males and released one who claimed he was a hitchhiker. The driver was held.The driver has been identified as a U.S. citizen who flew from Mexico to Chicago on Tuesday and then rented a car in Fort Myers, Florida, said Department of Homeland Security spokesman Brian Doyle. Doyle said he did not know how the man got from Chicago to Fort Myers.Doyle did confirm the car had more than one package, contrary to earlier reports. Just how many was not clear.Video from the scene showed members of the U.S. Capitol Police bomb squad approach the gray 2005 Chevrolet Impala, then unreel detonation cord from the vehicle. At 1:11 p.m., the packages were "disrupted," a police term for destroyed. The back door on the driver's side blew open, and glass flew from the car. Shortly after the explosion, bomb squad members, dressed in green hazardous material suits, combed through the vehicle, rifling through the trunk and the interior of the car. Federal law enforcement officials are considering filing charges against the driver.They likely would involve a violation of the federal law against making a threat and giving false information about an attempt to destroy property with a bomb, said federal law enforcement authorities familiar with similar threats to government facilities in Washington.The maximum penalty for a conviction on such a charge is 10 years in prison.Sgt. Jessica Gissubel, spokeswoman for the U.S. Capitol Police, said the men had parked the car around 10:50 a.m. and "made comments to our officers which rose their suspicion."
