Tripoli — The former spokesman of Muammar Gaddafi's government has been captured, exactly a year after the death of the Libyan dictator, the prime minister's office said on Saturday.

Moussa Ibrahim has been arrested by forces belonging to the Libyan government in the town of Tarhouna, 70 km (40 miles) south of Tripoli, and he is being transferred to Tripoli to begin interrogation, the statement said.

Ibrahim's whereabouts have been unknown since the fall of Tripoli in August 2011 but there have been past reports of his capture.

Saturday marks one year since Gaddafi's capture and death in his hometown Sirte, after he was caught hiding in a drain pipe.
