A FIFA member is the source of thousands of illegal ticket sales at the World Cup finals, a Brazilian police chief said Thursday.
Police commissioner Fabio Barucke said "someone from FIFA" and "an intermediary from Match Hospitality", FIFA's ticket agency, channelled the millions of dollars worth of tickets onto the black market.
The FIFA official, who was not identified, is believed to be staying at the Copacabana Palace, a luxury Rio de Janeiro hotel, Barcuke told reporters.
Police made 11 arrests Tuesday of people accused of selling tickets that may have been obtained through a contact at world football's governing body.
A police investigation, dubbed "Operation Jules Rimet" after the former French FIFA president, was launched without FIFA's knowledge, the police chief said.
However, following the arrests "we are now calling for Fifa's assistance to help us identify this FIFA person, a foreigner staying in the Copacabana Palace hotel," Barucke said.
Initially, police thought that Mohamadou Lamine Fofana, a Franco-Algerian national based in Dubai, was the source of the trafficking, Barucke said.
"But after his arrest we realized there was someone above him from Fifa with an intermediary at Match Hospitality," he added.
"We want to identify the last link in the chain, from the ticket touts at the stadiums, right through to those who are above Lamine Fofona and who passed the tickets on to him," said Barucke.
He added: "We have indications that at least one person from Fifa passed on tickets" to Match Hospitality.
Brazilian authorities said Wednesday they suspected members of the Brazilian, Argentine and Spanish football federations were involved in illegally selling tickets normally reserved for sponsors, football federations, players and non-government organizations.
Marcos Kac, the Rio de Janeiro investigating magistrate in charge of the inquiry said Wednesday that at least 1,000 tickets per game were involved with a basic price of 1,000 euros ($1,365).
Fifa spokeswoman Delia Fischer said Thursday the world body was waiting to get more information on the Brazilian investigation before commenting.
The brother and agent of former football star Ronaldinho, Roberto de Assis Moreira, faces questioning in the case, but is not under investigation, Kac said.
