Muammar Gaddafi's son Saadi who fled abroad during Libya's 2011 revolution and was extradited from Niger last year appeared in a Tripoli court on Sunday at the start of a trial on murder charges but the judge adjourned his case until July.
Saadi, who had a brief career as a soccer player in Italy and had the reputation of a playboy during his father's long rule, appeared in the Tripoli courtroom wearing a blue jumpsuit and watched the proceedings from behind bars.
"The trial of Saadi Gaddafi has been adjourned today by the court of south Tripoli until July 19," the chief of the investigation office of the attorney-general, Sadiq Al-Sour, told Reuters. "The defence lawyers had asked for more time to read the case file and prepare for a plea."
Saadi Gaddafi faces charges of killing a football player and unlawful imprisonment.
Since the 2011 fall of Gaddafi, Libya has slipped deeper into chaos with two rival governments and the armed factions that back them fighting for control. Islamist militants have gained ground during the period of lawlessness.
Gaddafi's more prominent son, Saif al-Islam, is being held captive by fighters in the western Libyan town of Zintan. They refuse to hand him over to a government they deem too weak to hold him.
Since escaping Libya in 2011, Saadi had been held under house arrest in the Niger capital Niamey. Libyan authorities believe he was active from there in fomenting unrest in southern Libya. He was extradited back to Libya in March 2014.
