Libya Detains Suspect in Benghazi Attack

FBI is involved

A man suspected of involvement in the September attack on the U.S. diplomatic compound in Benghazi is being held in Libya, according to two sources who have spoken with CNN.

Both sources confirmed the man's name as Faraj al-Shibli (also spelled Chalabi). One of the sources, who has been briefed on the arrest by Western intelligence officials, said al-Shibli was detained within the past two days and had recently returned from a trip to Pakistan.

A Libyan source also confirmed that al-Shibli was in custody in the north African nation. The FBI was given direct access to him, and it interviewed him recently in the presence of Libyan authorities, according to the Libyan source.
