No explosives found with man in custody near Pentagon
A suspicious man with a backpack prompted authorities to temporarily close major highways around the Pentagon Friday, but a search of the backpack turned up no explosives.
The man, described as a U.S. resident in his 20s, was taken into custody in the predawn hours after he ran from police in Arlington National Cemetery near the Pentagon. Authorities traced him to a car found abandoned near a Pentagon parking lot.
Hours later, the unnamed man was in police custody but had had not been charged with any crime, and the FBI said nothing suspicious was found in the car.
ABC News reported that the backpack contained a substance initially believed to be the explosive compound ammonium nitrate, as well as spent bullet shells and written material referring to al Qaeda and the Taliban.
However, FBI special agent Brenda Heck told reporters that the substance in the backpack was an unknown inert material but it would require further investigation. She said there was no device in the backpack.
