SECRECY surrounds a Fifa-led investigation into the alleged fixed matches involving Bafana Bafana.

The probe, which begins in Johannesburg today, is headed by Fifa's super sleuth Chris Eaton, and will cover allegations of five Bafana matches played early in 2010 ahead of the World Cup as well as other possible corrupt games in Southern Africa.

Eaton is assisted by Terry Steans, who is also from Fifa's investigations department, and Mlungisi Ncame, Safa's head of security.

Among the witnesses to be interviewed by the investigators are Bafana Bafana coach Pitso Mosimane, former manager Sipho Nkumane and national teams' head Lindile "Ace" Kika.

Former coach Carlos Alberto Parreira will also give evidence, but it could not be established yesterday if the former Bafana coach will be there in person or send a written statement.

The investigation will focus on the appointment of referees for the five suspect Bafana games.

Former Safa chief executive Leslie Sedibe has said he was not involved in the appointment of the referees, saying he delegated Kika to deal with the matter.

Sedibe will also make a submission to the investigators. Kika has denied any wrong-doing. The referees were appointed by a shadowy sports marketing group, Football4U, which was given the task by the South African Football Association.

The match-fixing allegations centre on Bafana Bafana matches between May and June last year against Thailand, Bulgaria, Colombia and Guatemala.

Football4U was controlled by Wilson Raj Perumal, a Singaporean who has since been jailed in Finland for fixing games in that country.
