The Libyan, Nazih Al-Ragye, better known as Abu-Anas Al-Liby, is a suspect in the 1998 bombings of the US embassies in Kenya and Tanzania that killed 224 civilians.
He was seized by a US Army Delta Force squad on the streets of Tripoli on October 5 and whisked onto a Navy ship in the Mediterranean Sea.
He was flown to the United States and handed over to civilian law enforcement over the weekend and brought directly to the New York area, said US Attorney Preet Bharara, the chief federal prosecutor for Manhattan.
Al-Liby is expected to appear before a judge on Tuesday, Bharara said in a statement. A criminal indictment was filed in 2001 against Al-Liby and others suspected in the embassy bombings.
US officials initially said they expected Al-Liby would be held aboard ship for weeks or months while under questioning by an elite US interagency team known as the High-Value Target Interrogation Group, or HIG.
But a law enforcement official said that, soon after his capture, it became clear to interrogators that Al-Liby suffered from several pre-existing chronic health conditions.
The official said his transfer to the custody of civilian authorities in the United States was necessary because medical facilities aboard ship were not sophisticated enough to provide adequate care.
Al-Liby’s wife has said in media interviews that he suffers from Hepatitis C.
David Patton, the chief public defender for New York who had requested that a judge appoint a defense lawyer for Al-Liby, had no immediate comment on Al-Liby’s transfer.
US District Judge Lewis Kaplan in Manhattan declined on Friday to assign a court-appointed attorney to Al-Liby until he had been formally arrested by law enforcement.
It was not immediately known whether Al-Liby cooperated with US interrogators or provided them with intelligence of any value. He was in military custody for about 10 days.
Shortly after Al-Liby was captured, Republican US Senator Lindsey Graham suggested he should be held as an enemy combatant and interrogated at the US detention camp at Guantanamo Bay, Cuba, which President Barack Obama has vowed to close.
In the past, local authorities in New York and national politicians expressed concern that the imprisonment and trial of high-level Al-Qaeda suspects in New York or other US cities could provoke retaliatory attacks against the US mainland.
Over the past year, however, other high-level Al-Qaeda suspects, including a close associate of the late Osama Bin Laden and a notorious London-based preacher known as Abu Hamza Al-Masri, have been extradited to New York to face federal court trials with little apparent impact on security.
Senator Patrick Leahy, chairman of the Senate Judiciary Committee, applauded the decision to try Al-Liby in a civilian court. It “shows that the United States acts out of strength and not out of fear. We are not afraid of terrorists, nor are we afraid to bring them to justice in our courts,” he said.
US officials say Al-Liby remained a significant figure in Al-Qaeda. They said he served as a liaison between militant groups in Libya and North Africa and Ayman Al-Zawahiri, the Egyptian physician who now leads what remains of Al-Qaeda’s core organization based in Pakistan.
In the wake of the September 11, 2001 Al-Qaeda attacks on New York and Washington DC, the US government offered a USD 25 million reward for information leading to Al-Liby’s capture. But later the reward was reduced to USD 5 million.
A group of Libyan gunmen who briefly seized Prime Minister Ali Zeidan from a Tripoli hotel last Thursday said they did so because of his government’s role in the US capture of Al-Liby.
