Roads around the Pentagon were closed today after police detained a man in Arlington National Cemetery and found his car in bushes near the Pentagon. Park police stopped the man overnight because the cemetery was closed, and found that he was carrying what was believed at the time to be ammonium nitrate and spent automatic weapon ammunition, according to ABC News. An FBI agent now says "the products found are determined right now to be inert." He was also reportedly carrying a notebook with phrases like “Taliban rules” and “defeated coalition forces” written in it.
The man allegedly told police that there were other “devices” in the area. Police found his 2011 red Nissan near the Pentagon's north parking lot with something that looked "like a bomb” inside, officials told the Washington Post. The car was “rendered safe” by the bomb disposal unit, authorities tell CBS. The FBI agent says no suspicious items were found in the car. (Read more bomb scare stories.)
