Mexican authorities are investigating whether the owner of a Mexican oil services company that allegedly defrauded Citigroup used his professional soccer team to launder money.

An official with the Attorney General's Office says Amado Yanez owns Oceanografia SA de CV and the White Roosters, a Queretaro-based team in Mexico's first division soccer league.

The official said Monday that fiscal authorities are reviewing the team's financial and administrative structures. He agreed to discuss the investigation only if granted anonymity because he was not authorized to publicly discuss the case.

Authorities are also investigating Oceanografia after it allegedly overstated by $400 million the business it was doing with Mexico's state-owned oil company to get loans from Banamex, Citigroup's largest Mexican bank.

Oceanografia was suspended from getting more Pemex contracts in February.
