Former Fifa vice-president Jack Warner, 72, channelled US$10 million (S$13.5 million ) - paid by the South African government in its efforts to host the 2010 World Cup - into his pocket, according to documents the BBC saw.
The US$10 million, US prosecutors said, was reported to be a bribe to secure the 2010 World Cup which the government and its football association has denied.
The South African government insists this was a legitimate payment to promote Caribbean football.
Additionally, pressure is also growing on Danny Jordaan, president of the South African Football Association and the organiser of the 2010 World Cup in South Africa, to explain his role on the Fifa bribery scandal after a leaked letter showed that he suggested the US$10 million payment to Caribbean football.
Among the documents BBC saw, secretary-general of Fifa Jerome Valcke had written to a South African minister asking for the status on the money transfer.
Valcke also mentioned that outgoing Fifa president Sepp Blatter and then South African President Thabo Mbeki had discussed the matter.
Here is the tangled web surrounding the man at the centre of the growing controversy shrouding the world football governing body, as it emerged on Wednesday that the new successor to Blatter could be elected on Dec 16, 2015.
Who is Jack Warner?
He is said to be one of the most experienced members of Fifa's executive committee until he stepped down in 2011 and had served as its vice-president for 14 years.
Warner, once a history teacher, was also the former Minister of National Security of Trinidad and Tobago from 2010 to 2013 and was an elected member of the country's parliament from November 2007 to April 2013.
How Warner pocketed the US$10 million using a football academy
Reports said South Africa invested the money through Fifa to promote football in the Caribbean.
And the money was intended to be spent on a Centre of Excellence - a football academy in Trinidad and Tobago.
Ironically, the same centre is owned by Warner.
The centre was supposed to train a new generation of footballers from around the Caribbean, reports said.
The funds - paid to Fifa - was moved to the account of the Confederation of North, Central America and Caribbean Association Football - a body controlled by Warner himself.
Now, he is among the 14 Fifa officials charged by US authorities for alleged corruption activities.
What Warner used the money for
The BBC reported it had seen evidence showing Warner had used the money for cash withdrawals, personal loans and to launder money.
"The papers seen by the BBC detail three wire transfers by Fifa," the report said.
Three transactions revealed that on Jan 4, Feb 1 and Mar 10, 2008, funds amounting to US$10 million from Fifa accounts were transferred into Concacaf accounts, reported the BBC.
Where the US$10 million went to:
Evidence BBC had seen, pointed to JTA, a supermarket in Trinidad, which reportedly received US$4.86 million.
The money was paid in instalments from January 2008 to March 2009.
The largest amount was US$1.35 million, paid in February 2008.
The money was paid back to Warner in local currency, BBC reported.
About US$1.6 million was used to pay his credit cards and personal loans.
He was his own virtual bank, providing himself US$410,000 - his largest personal loan.
Some US$360,000 of the Fifa money was withdrawn by people connected to Warner.
US$87,000 - his largest credit card payment.
Warner is also facing fresh allegations that he had diverted US$750,000 - donated by Fifa and the Korean Football Association for 2010 Haiti earthquake victims - into the Trinidad & Tobago Football Federation instead, which he also controlled.
