FIFA has hired former FBI director Louis Freeh's investigations agency to gather evidence of alleged bribery involving Mohamed bin Hammam and Jack Warner.

FIFA says Freeh Group International Europe will ''work under the direct supervision'' of FIFA ethics committee member Robert Torres, a judge from Guam.

Freeh founded FGI after serving the Federal Bureau of Investigation as director from 1993-2001.

Investigators will interview Caribbean Football Union officials who allegedly were offered $40,000 cash to back bin Hammam's FIFA presidential bid.

Bin Hammam withdraw his candidacy last Sunday, hours before FIFA's ethics panel provisionally suspended him and Warner.

FIFA President Sepp Blatter was re-elected unopposed on Wednesday.
