Farooque Ahmed, the man who was arrested on terrorism charges as part of a federal sting operation in October, has pled not guilty, CNN reports. Ahmed was arraigned in an Alexandria district court this morning on charges of attempting to provide material support to a designated terrorist organization, collecting information to assist in planning a terrorist attack on a transit facility and attempting to provide material support “to help carry out multiple bombings to cause mass casualties” on Metro. Ahmed reportedly said nothing other than “yes, sir” when asked to confirm his signature on a document. Ahmed’s jury trial has been scheduled to begin on April 11, 2011.
