However, al Chalabi was released June 12 based on claims that there was a lack of evidence to hold him custody.
A U.S. official said the U.S. government has evidence al Chalabi was linked to the Benghazi attack but did not provide that information to the Libyan government. It could not be learned why the evidence was not used to hold the suspect.
The FBI is conducting an investigation into the Benghazi attack. An FBI spokeswoman declined to comment on al Chalabi’s release.
Chalabi, who was arrested by the Libyans in March after returning from Pakistan, is believed by U.S. intelligence and law enforcement officials to be one of the people who organized the attack on the diplomatic compound.
