Rebel "special forces" arrested Seif al-Islam Gadhafi - a son of Libyan leader Moammar Gadhafi indicted along with his father on crimes against humanity charges, the prosecutor of the International Criminal Court said early Monday.
Seif Gadhafi was indicted with his father and Libya's intelligence chief earlier this year for allegedly ordering, planning and participating in illegal attacks on civilians in the early days of the violent crackdown on anti-regime protesters.
Prosecutor Luis Moreno-Ocampo told The Associated Press that Seif Gadhafi had been detained by "rebel special forces." He declined to give more details of the arrest or the source of the information.
"Tomorrow morning we will talk to them," Moreno-Ocampo said of the rebels. "It is time for justice, not revenge."
Seif Gadhafi's detention came as rebels advanced into the Libyan capital Tripoli with little resistance and a rebel leader said the unit in charge of protecting Gadhafi and Tripoli had surrendered and joined the revolt, allowing the opposition force to move in freely
Moreno-Ocampo said he had no word on the whereabouts of Libyan leader Gadhafi.
"We hope that Moammar Gadhafi is also arrested and also faces justice," he said. "There is no more impunity for these crimes."
