AFP, SINGAPORE: Three people whose alleged fraud wiped $5.6 billion off the Singapore stock exchange were charged Friday with manipulating the market. Malaysian John Soh Chee Wen and Singaporean Quah Su-Ling are accused of being the "masterminds" behind a plot that involved using over 180 trading accounts to inflate the share prices of three companies, authorities said. Calling it the largest market manipulation in the city-state's history, prosecutors, police and the central bank said the "complex and elaborate fraud" involved the shares of Blumont Group, Asiasons Capital and LionGold Corp. Soh and Quah used the shares as collateral, convincing several banks including Goldman Sachs to extend more than Sg$170 million (US$119 million) credit to finance their scheme, a statement added.
