A SWISS judge investigating the transfer of hundreds of millions of dollars to Switzerland by the regime of the late Sani Abacha has questioned his son, Mohammed Abacha. Judge George Zecchin arrived in Nigeria and met Abacha after he was flown to Abuja from Lagos where he is currently detained on unrelated murder charges. A Nigerian court last month rejected a request from Switzerland to extradite Abacha, the eldest surviving son of the late Nigerian dictator, to face charges over the alleged illegal transfer of hundreds of millions of dollars to Switzerland by the regime. Authorities in Switzerland last year froze some $650m in accounts linked to Abacha. Luxembourg authorities froze another 690m euros (around $600m) and authorities in Lichtenstein froze around $100m.The Nigerian government has estimated that around $4bn disappeared from public funds under the Abacha regime of which around $3bn is believed to have benn sent abroad. – AFP
