The issue is that there is already a case before the (ICC) court,MBT," he said. "Now Libya has a legal obligation under international law to present a challenge to say: 'We have this suspect and he will be dealt with under our national laws."

"They will need to show that they have a serious,MBT calzature, genuine legal system capable of functioning fairly in this case," he said.

Seif al-Islam,MBT scarpe, who was once the face of reform in Libya and who led his father's drive to emerge from pariah status over the last decade, was captured by fighters from the small western mountain town of Zintan who had tracked him to the desert in the south of the country.

He was then flown to Zintan, 85 miles (150 kilometres) southwest of Tripoli, where he remains in a secret location.
