Zurich - FIFA has appointed former United States attorney Michael J. Garcia as lead prosecutor to investigate allegations of corruption in world football.
FIFA president Sepp Blatter confirmed the appointment by Twitter on Tuesday.
One of Garcia's first tasks will be to inspect a Swiss court document on a Soccer World Cup kickbacks scandal to evaluate the behaviour of Blatter and other senior officials in the affair.
Garcia should have authority to order fresh probes into other old cases, including claims about how FIFA executive committee members awarded hosting rights for the 2018 and 2022 World Cups.
His appointment by that same ruling board is seen as a crucial step in Blatter's promised anti-corruption reforms.
FIFA also selected German judge Joachim Eckert to chair the judging chamber of its ethics court.
Garcia and Eckert are seen as key independent figures from outside the so-called "football family" who can help restore FIFA's credibility after bribery and vote-buying scandals.
Blatter's ruling board agreed to create a two-chamber ethics court to prosecute cases more effectively after a panel of anti-corruption experts advising FIFA said previous cases were "insufficiently investigated."
The 13-member panel, led by Swiss law professor Mark Pieth, wants Garcia to examine claims surrounding how Russia and Qatar came to get World Cup hosting rights in a December 2010 poll of FIFA's executive committee.
Several senior FIFA officials were reported to have received payments or sought unethical favors from bidders, and Blatter has acknowledged that some breached bidding rules by joining a pact to back Qatar and the failed Spain-Portugal bid.
Garcia and Eckert had to fulfill a FIFA statute that neither they, nor their families, had a paid connection to football in the past four years.
Garcia was linked to an expected vacancy to lead the US Federal Bureau of Investigation last year, before President Barack Obama extended the term of 10-year incumbent Robert Mueller.
During the administration of President George W. Bush, Garcia headed the 20 000-employee Immigrations and Customs Enforcement agency in the Department of Homeland Security.
Eckert, who was a presiding state court judge in Munich, is a specialist in high-profile bribery cases including one which exposed billion-dollar payments made by German telecommunications firm Siemens.
Pieth's group suggested four candidates for each of the positions to be decided on Tuesday, including Eckert. FIFA looked elsewhere for Garcia's nomination.
FIFA declined to appoint war crimes prosecutor Luis Moreno-Ocampo of Argentina who was widely reported to be the advisory panel's preferred choice.
