He had gone underground after Tripoli fell to revolutionary forces and issued audio recordings to try to rally support for his father.
“First we have to verify if it really is him and that he’s actually been arrested this time,” the spokesman, Fadi El Abdallah, said. “If they decide they want to try the suspect in Libya instead of at the ICC, there’s a necessary process.”
He said the Libyans could formally request that the case be transferred, then ICC judges would make a decision.
“The main criteria is that he generally be prosecuted for the same crimes,” the spokesman said. “For us there’s an obligation, a legal obligation under international law, for the national government to cooperate with the ICC.”
Libya’s Information Minister Mahmoud Shammam said the NTC had not taken an official position yet, but in his personal view, Seif al-Islam “is an outlaw and should be tried in front of the Libyan Court, by Libyan people and by Libyan justice.”
