Zambia's investigating and prosecuting body on corruption cases has said it has enough evidence before the court proving that former Zambian president Fredrick Chiluba and two others stole public funds amounting to almost 500,000 U. S. dollars, the Zambia Daily Mail reported on Monday. The Task Force on Corruption said evidence submitted proves beyond reasonable doubt that the former president stole the money he was accused of, Daily Mail said. Task Force on Corruption Prosecutor Mutembo Nchito said in his submissions that the nature of the crime 'disclosed a mammoth and well-orchestrated machinery set up to defraud government.' According to the submissions, the country's former intelligence chief Xavier Chungu was allegedly at the center of proceedings in which Chiluba and others are charged with theft of public funds. The state prosecutor said the former intelligence chief testified that 'everything he did for Chiluba was of security nature, including paying money for the former president's children.' Chiluba and two directors of a defunct financial institution, Aaron Chungu and Faustin Kabwe, are charged on 12 counts of theft.
