(REUTERS) - The US Justice Department on Friday (July 14) filed a lawsuit seeking to recover assets that include a US$50 million (S$69m) Manhattan apartment and an US$80 million yacht that it said were bought using money generated from a scheme to pay millions of dollars in bribes to a former Nigerian oil minister.
The civil lawsuit, filed in federal court in Houston, alleged that two Nigerian businessmen conspired with others to pay bribes to the minister, Diezani Alison-Madueke, who oversaw the African country's state-owned oil company.
The lawsuit said that in return, Alison-Madueke steered lucrative contracts with a subsidiary of Nigerian National Petroleum Corp to companies owned by the two businessmen, Kolawole Akanni Aluko and Olajide Omokore.
Despite being unqualified and in some instances failing entirely to perform services under the contracts, these companies received more than US$1.5 billion in revenues through the sale of crude oil, the lawsuit said.
The Justice Department said that Aluko and Okokore then laundered their illicit revenues through the United States and used the money to buy US$144 million (S$197m) in assets including the Manhattan condominium and the US$80 million yacht, the Galactica Star.
The condominium is located in One57, a skyscraper located near Central Park on a street in Midtown Manhattan that is known as "Billionaire's Row."
Acting Assistant Attorney General Blanco said in a statement that the case demonstrated the Justice Department's commitment to trading and recovering corruption proceeds.
"The United States is not a safe haven for the proceeds of corruption," he said.
Following a mortgage default, lender Banque Havilland SA launched foreclosure proceedings on the condominium in January. It is scheduled to be up for public auction on July 19, according to the lawsuit.
Alison-Madueke was charged with money laundering in Nigeria, the country's financial crimes agency said in April. She previously denied to Reuters any wrongdoing when questioned about missing public funds and corruption allegations.
Lawyers for Aluko and Omokore could not be immediately identified. They are not defendants in the lawsuit, which is a civil forfeiture action.
The lawsuit was brought as part of Justice Department's Kleptocracy Asset Recovery Initiative, which seeks the forfeiture of the proceeds of foreign corruption.
