TRIPOLI, Aug. 4 -- Saadi Gaddafi, son of Libya's former leader Muammar Gaddafi, has appeared in a video depicting his torture and being insulted inside a Libyan jail.

An amateur video posted on social media showed Saadi blindfolded while a group of people beat and insulted him. It seemed he was held in a prison facility, most likely the Al-Hadba correction facility where most of Gaddafi's former officials are detained.

Libyan Attorney General Monday issued a decision to investigate the video and identify the people shown torturing Saadi in the video.

The Libyan National Committee of Human Rights "condemned similar violations towards prisoners in detention centers of the country's judicial authorities and the Attorney General."

Prosecutors say Saadi, who headed a brigade of special forces during the 2011 revolt, faces abduction and rape charges as well as charges of abusing his post.

Saadi is also suspected of killing Bashir al-Riyani, a popular Libyan football player who was a vocal critic of Gaddafi's regime in 2005.

Besides his political life, Saadi was best known as head of Libya's football federation, and a player who paid his way into Italy's top division.

A court in Tripoli Tuesday sentenced 37 former officials from the Gaddafi regime to death, imprisonment and fines for crimes including murder, incitement to commit genocide, and embezzlement of public funds, including Saadi's brother Saif Islam Gaddafi.
