BEIJING, March 15 (Xinhuanet) -- Libyan authorities have detained a man investigators believe could be an important witness or suspect in the attacks on US outposts in Benghazi last September.

The man, a Libyan national identified as Faraj al-Chalabi, fled to Pakistan after the attacks and only recently returned to Libya. It is still unclear precisely what role he played. Though US sources in Washington said they did not believe he was a principal instigator or a front-line leader.
