Washington (CNN) -- The man accused of attempting to help bomb subway systems in the Washington area will remain in federal custody after his court-appointed attorneys declined Friday to challenge his continued detention.
Farooque Ahmed appeared in a federal courtroom in Alexandria, Virginia. He wore a green prison jumpsuit. He did not speak during the proceeding, which lasted less than five minutes.
Magistrate Judge John Anderson said Ahmed will remain in custody pending further proceedings. No additional hearings were scheduled.
Ahmed, 34, of Ashburn, Virginia, was arrested Wednesday in connection with an alleged plot to carry out terrorist bombings of Washington Metro stations in the general vicinity of the Pentagon.
The FBI said he had conducted surveillance for undercover agents whom he believed to be al Qaeda co-conspirators.
Ahmed, a naturalized citizen, is a native of Pakistan. He holds a college degree in computer science and had been employed at a telecommunications company in suburban Virginia.
