Fox News is reporting authorities have a suspect in custody after finding a backpack which may contain an explosive chemical near the Pentagon in Arlington, Va.
A source with knowledge of the investigation told Fox News that authorities were alerted to a suspicious vehicle in the area early Friday morning. A backpack containing what they believe is five pounds of ammonium nitrate was found outside the vehicle, the source said, though authorities are still trying to determine what the material is.
A notebook was also found at the scene and contained threatening words like “Al Qaeda” and “Taliban,” Fox News has learned.
The man arrested is a naturalized U.S. citizen who came to the country from Ethiopia, a source told MyFoxDC.com.
