He is being held in the militia stronghold of Zintan.
But as celebrations continue over the arrest of Saif al-Islam, the question remains: where will Colonel Gaddafi’s son face justice?
Libyan authorities are adamant; they want a trial on home soil – a view widely shared in the country.
“I hope he is prosecuted in the Libyan courts so he can have a taste of his own medicine and feel the same as the Libyans he has unjustly imprisoned,” said Zintan resident Abu Bakr Mohammed. “Libyan prisons were inhuman. This is what I wish. I hope it will happen.”
Fighters who seized him in the southern desert and flew him to Zintan in Libya’s western mountains say Saif won’t meet the same fate as his father who was killed during his capture.
But angry crowds waiting for him on the runway as he arrived show the strength of feeling and Saif could face the death penalty after a trial in Libya.
That is not an option at the International Criminal Court which has indicted him for alleged crimes against humanity. Its prosecutor Luis Moreno Ocampo is due in Libya next week.
