(CNN) -- FIFA have asked Caribbean soccer officials to clarify their role in a meeting that resulted in former presidential candidate Mohamed Bin Hammam being banned from the sport for life.
The Qatari was found guilty of offering cash for votes at the summit by football's governing body and barred from having any involvement with the game, despite protesting his innocence.
In a statement given to CNN, FIFA said they had given Caribbean Football Union (CFU) officials 48 hours to provide relevant information about the meeting, or face similar sanctions.
It read: "FIFA sent a letter yesterday (25) July to all CFU associations, asking the associations, their presidents, and any of their members with knowledge of anything that transpired during the meetings held on 10 and 11 May in Trinidad and Tobago to provide and report all relevant information in their possession within 48 hours.
"Truthful and complete reporting will be considered in mitigation by the Ethics Committee when deciding on potential sanctions. Any person who has relevant information but does not come forward during this 48 hour period will be subject to the full range of sanctions.
"Following this 48 hour period, the Ethics Committee will be asked to open the necessary ethics proceedings."
Bin Hammam had been accused of illicitly plotting with Jack Warner, the former head of the association in charge of football in North and Central America and the Caribbean, to help secure votes in the region ahead of the presidential vote.
Out of 25 Caribbean associations, Cuba were the only one that didn't attend the meeting in Port of Spain, where it is alleged Bin Hammam gave or offered cash gifts of around 40,000 US dollars.
The investigation against Warner was dropped -- under the presumption of innocence -- after the Trinidadian resigned in June.
Bin Hammam was suspended pending an investigation in May and subsequently dropped his bid to become FIFA president, leaving Sepp Blatter unopposed to win a fourth term.
But the 62-year-old who played a key role in controversially securing the 2022 World Cup for his native Qatar, has vowed to fight on to clear his name and urged Asia's football family to back him.
In an interview with Sky News earlier this week Bin Hammam compared Blatter to a "dictator" who was out to get revenge.
