The Libyan government announced Thursday via its Facebook page that Saadi "was handed to Libya and is now in the custody of the Libyan judicial police." He is currently being held at a jail in Tripoli.
Libyan Prime Minister Ali Zeidan explained that the extradition was based on evidence that Saadi was involved in "communications and practices targeting Libya's security and aimed at destabilizing Libya."
While in Niger, Saadi reportedly lived in a secure guard house in the capital city of Niamey. He was placed under house arrest after making a televised phone call in February 2012, during which he claimed to be in regular contact with Libyans unhappy with the new government and warned that an uprising in Libya was imminent.
Saadi is one of Gadhafi's seven sons. Prior to the Libyan revolution that toppled his father, Saadi was a professional soccer player and businessman.
