Authorities in the US claim a conspiracy to obtain contracts from Venezuela's state oil company involved $US1 billion, traced to an oil magnate.
US authorities have traced more than $US1 billion ($A1.39 billion) to a conspiracy involving a Venezuelan magnate who allegedly paid bribes to obtain contracts from Venezuelan state oil company PDVSA.
The details, in US court papers made public on Monday, came a day after the US Justice Department confirmed that authorities had arrested Roberto Rincon, a Venezuelan citizen who is president of Texas-based Tradequip Services & Marine.
According to an indictment, Rincon and Venezuelan businessman Abraham Jose Shiera Bastidas conspired to pay bribes to officials to secure contracts from Petroleos de Venezuela S.A. (PDVSA), Venezuela's state-owned oil company.
The indictment said five PDVSA officials, whom it did not name, received hundreds of thousands of dollars in bribes made principally in the form of wire transfers but also through mortgage payments, airlines tickets and, in one case, whiskey.
The bribes also included a $US14,502 reservation for a PDVSA official at the luxury Fontainebleau Hotel in Miami, the indictment said.
According to a court order in the case, from 2009 to 2014, more than $US1 billion was traced to the conspiracy, $US750 million of which was traced to Rincon, who lives in Texas.
To one official alone, Rincon paid $US2.5 million in bribes, the order said.
The indictment charges that Rincon, 55, and Shiera, 52, violated the Foreign Corrupt Practices Act and conspired to launder money.
"Mr Rincon denies the allegations made against him in the indictment and looks forward to the opportunity to challenge the government's case," said Samuel Louis, his lawyer.
A lawyer for Shiera, who resides in Florida, did not respond to a request for comment. Shiera is the manager of Vertix Instrumentos, a Venezuelan supplier to the oil sector.
Both men were arrested on December 16 and have been held without bail.
