Eni investigated on Libyan corruption MILAN, Italy, April 6 (UPI) -- Italian energy company Eni said it was being investigated by the U.S. Securities and Exchange Commission for alleged illegal payments to Libyan officials. Eni in a 20-F annual report said it received a "judicial request" from the U.S. Securities and Exchange Commission to hand over documents related to its work in Libya from 2008 to 2011. "The subpoena is related to an ongoing investigation without further clarifications nor specific alleged violations in connection to 'certain illicit payments to Libyan officials' possibly violating the US Foreign Corruption Practice Act," the filing read. Much of Libya's energy sector shut down last year when NATO forces imposed a no-fly zone to respond to Moammar Gadhafi's crackdown on an uprising against his regime. Eni, one of the first energy companies to return to Libya last year, generated 13 percent of its revenue from operations there before the war. "At the end of December 2011, Eni received a request for the collection of further documentation aiming at integrating the subpoena previously received," the company said in the filing. Eni is fully collaborating with the U.S. SEC. Libya's Interim Oil Minister Abdulrahman Ben Yezza was the former chairman for Eni Oil Co., a joint venture with the Libyan National Oil Corp.
