Former Fifa vice-president Jack Warner has left jail in Trinidad in an ambulance, according to reports.
Warner, who was forced to spend a night in the cells after complications with his bail terms, was one of more than a dozen executives charged by US authorities in a major corruption investigation.
A prison official said that Warner had complained of exhaustion.
He is facing charges in the States which include conspiracy to defraud and engaging in racketeering. He has not entered a plea and is expected to appear in court in July.
Worried that their reputations will be tarnished by their links to Fifa, major sponsors are demanding football's global governing body clean up its act.
Visa has even warned it is prepared to jump ship, saying it expects the organisation to take "swift and immediate steps to address" its issues.
Coca-Cola also made it clear it is unhappy with the scandals rocking the organisation it and others support with millions of dollars a year.

Sepp Blatter will put himself forward for a fifth term as Fifa president tomorrow after rejecting calls to stand down in light of the corruption scandals.
Should Blatter emerge victorious the crisis in football is expected to worsen. European football bosses at Uefa are talking of breakaways and boycotting the World Cup.
ITV News Correspondent Paul Davies reports on whether England could join a World Cup boycott:
Fifa president Sepp Blatter ignored questions from journalists as he hurried to his car after the first day of the Fifa Congress.
Despite calls for his resignation, Blatter has remained resolute that he will remain at the helm. Fifa is due to vote for a new president tomorrow, with Blatter still in the running.
Here is the voting procedure at Friday's FIFA presidential election in Zurich:
- Sepp Blatter and Prince Ali Bin al Hussein will both have opportunities to address the Fifa Congress
- Each of Fifa's 209 associations should have a vote,although a few can face disqualification for reasons such as not playing in competitions
- If either candidate achieves two-thirds of the eligible vote in the first round then he wins outright - if there are 209 votes that means 139 to win outright
- If there is no outright victory, the winner will be whoever gains more votes in the second round
The US-led investigation into alleged corruption at Fifa has spread further afield, with offices being raided in Brazil and a former top official, Jack Warner, handing himself into police in Trinidad.
Thirteen of the 14 men charged by the FBI are from South American or Caribbean nations.
ITV News Washington Correspondent Robert Moore reports:
Sepp Blatter has blamed the corruption scandals engulfing Fifa on the "actions of individuals" and refused to quit as its president.
Speaking to the 65th Fifa Congress, he admitted that the arrests and the allegations of widespread corruption have brought "shame and humiliation" on football and stressed there was no place for it in the game.
Blatter was speaking publicly for the first time since the scandals broke yesterday and threw Fifa into crisis ahead of tomorrow's presidential election.
ITV News Sports Editor Steve Scott reports from Zurich, where the Congress is taking place:
Former England goalkeeper Peter Shilton told ITV News a European boycott of the World Cup must be, "a last resort."
Shilton, who played for England in three World Cups and holds the record for playing the most games for England, earning 125 caps said Fifa needed "fresh faces."
A former FA chairman has told ITV News that if Uefa wants to take serious action against Fifa they could boycott the upcoming World Cups, as the competition would be a "non-event" without European sides,
"The question is will Uefa be prepared to really bite the bullet and take some serious action, such as boycotting the next World Cups, unless they get genuine reform and unless [Sepp] Blatter goes subsequently?" David Bernstein asked.
"A World Cup is the basis of Fifa's power. The money and the power that Fifa has comes from that. A World Cup without European sides is nothing, it's really a non-event," he added.
Prince William says he would love to take Prince George to football matches, but he will have to "pass that by the missus".Read the full story ›
