NEW YORK: Citigroup Inc said it has received questions from US federal authorities investigating the role of financial institutions in alleged corruption and money laundering involving FIFA.

In an annual filing with securities regulators on Friday, Citigroup said it had received a subpoena from the US Attorney for the Eastern District of New York asking about banking relationships and transactions at its Citibank unit by "certain individuals" said to be involved in the alleged wrongdoing.

The company said it is cooperating with the investigation. A spokesman declined to comment further.
