Bombshell: Corrupt Oil Trader Turns On Diezani Alison-Madueke in Massive Africa Bribe Case In that same year, 2017, prosecutors from the Justice Department’s kleptocracy team filed a case in Houston to seize nearly $145 million worth of assets — including an $80 million, 215-foot yacht called the Galactica Star, a $50 million Billionaire’s Row apartment in New York and homes in California — that it said were purchased for the benefit of Nigeria’s oil minister, Diezani Alison-Madueke, with embezzled funds. Prosecutors said two associates of the minister set up companies shortly after she took office and were awarded contracts to sell large allotments of oil on global markets. The pair were awarded dozens of crude cargoes worth about $1.5 billion, according to the prosecutors. Nigeria received little of the proceeds of those sales, which prosecutors say were diverted for Madueke and her associates. One of the primary trading houses that stepped up to buy those cargoes, according to prosecutors: Glencore. They say that over the course of 2013 and 2014, Glencore bought 15 cargoes totaling 7 million barrels from the men, paying more than $800 million. Of that, they contend, roughly a third — $272 million — was diverted into an account at a Nigerian bank used for the purchases for Madueke.
