FIFA's head of security Chris Eaton is leaving football's governing body in a potential blow to the fight against match-fixing.
The Australian former Interpol officer has been at the forefront of FIFA's campaign against match-fixing and last month said that 2012 would be a fundamental year in the battle against one of the biggest threats facing the sport.
Eaton will join the Qatar-based International Centre for Sport Security as the organisation's director of sport security in May.
"I am sad to be leaving FIFA, but I am pleased to take with me an experience and knowledge that only FIFA within the current environment can provide," Eaton said in a FIFA statement on Friday.
"I am taking a new challenge that will encompass all sports, many of which could learn from FIFA's approach to combating match fixing."
Eaton, initially appointed to look after security issues at the 2010 World Cup in South Africa, has travelled the world in the last year leading the campaign against the rigging of games, which is usually orchestrated by illegal gambling rings.
He has called for greater co-operation from governments and police, saying that match-fixing is the work of organised criminal gangs which football's authorities cannot take on alone.
Under Eaton's blunt leadership, FIFA has offered an amnesty to players who have been involved in match-fixing and come forward with evidence.
A match-fixing hotline has also been set up and last year FIFA set up a 10-year agreement with Interpol.
Eaton has warned that criminal gangs are infiltrating football, setting up youth and referee training academies and buying small clubs in a bid to extend their influence.
"FIFA remains fully committed to the fight against match-fixing, an area where it has undertaken pioneering work," said the FIFA statement.comments
