U.S. special operations forces snatched Abu Anas al-Libi during a raid in Libya on Oct. 5 and has been held aboard a U.S. warship. A U.S. official told ABC News he arrived over the weekend under the control of the Justice Department.
The suspect, whose full name is Nazih Abdul-Hamed al-Ruqai, is in New York, where he has been indicted by the Southern District for his role in the bombings of U.S. embassies in Kenya and Tanzania in 1998. He is expected to be arraigned Tuesday.
Al-Libi has longstanding health issues and will get medical testing while in custody to determine whether he needs treatment, U.S. officials said.
Intelligence officials interrogated him for a week aboard the U.S.S. San Antonio in the Mediterranean. Interrogations at sea have replaced CIA black sites as the U.S. government's preferred method for holding suspected terrorists and questioning them without access to lawyers.
Al-Libi used to be on the FBI's most wanted terrorists list. His family says he was not in al Qaeda, but according to court documents, Al-Libi's ties to al Qaeda date back to the terrorist group's early years.
