Libya detains suspect in attacks on U.S. outposts in Benghazi

TRIPOLI/WASHINGTON (Reuters) - Libyan authorities have detained a man investigators believe could be an important witness or suspect in the attacks on U.S. outposts in Benghazi, Libya last September, according to people familiar with the matter.

The man, a Libyan national identified as Faraj al-Chalabi, fled to Pakistan after the attacks and only recently returned to Libya, said the sources, who include people in the United States and Libya close to the ongoing investigations. One Libyan security source said he was from Eastern Libya.
