Man arrested in plot to bomb Washington, D.C. subway

Suspect believed he was conspiring with al-Qaeda

Farooque Ahmed, 34, has been arrested for helping people he thought to be al-Qaeda members to plot a multi-bomb attack on the Washington, D.C. metro system. Ahmed conducted surveillance of metro stations on at least four occasions and suggested to his co-conspirators that they use wheeled suitcases for the bombs, rather than backpacks. Mr. Ahmed, a Pakistani-born U.S. citizen, is being held for attempting to provide material support to a terrorist organization, collecting information to assist in planning a terrorist attack, and attempting to provide material to support multiple bombings.
