Tripoli, Libya (CNN) -- Four staff members of the International Criminal Court were freed Monday after several weeks of detention in Libya, a Libyan liaison with the court said. Judge Sang-Hyun Song, the president of the court, met them on their release in the Libyan city of Zintan, said Ahmed Gehani. Melinda Taylor, a defense lawyer for the ICC, was detained in the city of Zintan after she was discovered carrying documents which the Libyan authorities said jeopardized Libyan national security. Three other court staff with her at the time have also been held. Taylor, an Australian citizen, is not in jail, but was placed under house arrest.
