A police report obtained by AFP showed that suspicions of impropriety against fallen FIFA boss Sepp Blatter over a controversial TV deal "were well-founded" despite Swiss prosecutors dropping the case.
Swiss legal chiefs suspected Blatter of having signed a "contract unfavourable to FIFA" with the Caribbean Football Union (CFU) then led by Jack Warner, who has since been banned from football for life and charged with corruption by American justice officials.
The deal had granted television rights for the 2010 and 2014 World Cups to the CFU for $600,000 (536,000 euros), an amount deemed to be significantly below market price.
"Blatter acted more in Warner's interests than those of FIFA," said one of the documents from the investigation.
"By failing to assert a claim by FIFA against the CFU when he found out about it, Blatter accepted that Warner would therefore illegally enrich himself at the expense of FIFA," added the investigators.
As a result of "the inaction of Blatter against the CFU or Warner, FIFA suffered damages amounting to $3.78 million."
