While Fifa officials were arrested in relation to US corruption charges, a separate probe has been launched into the allocation of the 2018 and 2022 World Cups. Here is the Swiss Attorney General's statement in full:
"The Office of the Attorney General of Switzerland (OAG) has opened criminal proceedings against persons unknown on suspicion of criminal mismanagement and of money laundering in connection with the allocation of the 2018 and 2022 Football World Cups. In the course of said proceedings, electronic data and documents were seized today at FIFA’s head office in Zurich.

"Today, on Wednesday 27 May 2015, the OAG has seized data and documents stored in IT systems at the Fédération Internationale de Football Association (FIFA) as part of a so-called “collection of evidence on cooperative basis”. That means that the party in possession of the data – in this case, FIFA – delivers the requested data to law enforcement authorities, or gives assistance in securing the data, thus facilitating an efficient and swift procedure. The collection of relevant bank documents had already been ordered beforehand at various financial institutes in Switzerland. The files seized today and the collected bank documents will serve criminal proceedings both in Switzerland and abroad.
"In the Swiss criminal proceedings, opened by the OAG on 10 March 2015, it is suspected that irregularities occurred in the allocation of the FIFA World Cups of 2018 and 2022. The corresponding unjust enrichment is suspected to have taken place at least partly in Switzerland. Furthermore, the head office of the damaged party, FIFA, is in Switzerland. For these reasons, investigations are being carried out on the suspicion of criminal mismanagement (Article 158 under 1, Section 3 Swiss Criminal Code / SCC). There are also suspicions of money laundering through Swiss bank accounts (Article 305bis, SCC). Subsequently to today’s seizure of files, the OAG and the Swiss Federal Criminal Police will be questioning 10 persons who took part in voting on the allocation of the 2018 and 2022 World Cups as members of the Executive Committee in 2010. These persons should be questioned as persons providing information.
Key players in the Qatar World Cup bid controversy
Key players in the Qatar World Cup bid controversy
1/5 Mohammed bin Hammam
The Qatari was the Asian Football Confederation president at the time of the 2010 vote. The Sunday Times alleged that documents showed he made payments to officials as part of a campaign to win support for the 2022 World Cup bid. He insisted he had no “official or unofficial” role with the bid. Fifa imposed a second life ban on him in December 2012, after his decision to quit all his football roles. This came after the Fifa ethics committee investigation found him guilty of “repeated violations” of the ethics code on conflicts of interest, while he was AFC president and while a member of the Fifa Exco between 2008-2011.
2/5 Jack Warner
The Trinidad & Tobago politician was forced to resign as a Fifa vice-president in 2011, after he and Bin Hammam were alleged to have paid bribes of £600,000 to Caribbean associations. He is also alleged to have helped Bin Hammam bribe Caribbean officials in return for support in his aim to oust Sepp Blatter.
3/5 Sepp Blatter
The long-standing Fifa president oversaw the bidding process to award Qatar the World Cup. Has since admitted awarding Qatar the cup was “a mistake”. He set up an executive committee task force to look into the World Cup in Qatar being moved to the winter because of the extreme summer temperature.
4/5 Lord Triesman
Former FA chairman. Alleged that, in exchange for voting for England to host the World Cup, Warner asked for money to build an education centre in Trinidad and to buy World Cup television rights for Haiti, and that Paraguay’s Nicolas Leoz asked for an honorary knighthood in exchange for their votes.
5/5 Michael Garcia
Former New York district attorney Michael Garcia was named Fifa’s chief independent ethics investigator. He spent a year investigating the organisation, and delivered a 350-page report on the 2018 and 2022 bidding processes in September. Called for greater transparency and culture change in Fifa.
"For reasons of criminal procedure (principle of proportionality), the procedure coordinated with the requested acts of the U.S. authorities was designed in such a way as to allow the procurement of any criminally relevant data in an effective manner, and to avoid any possible collusion. These measures were carried out simultaneously as a large number of persons involved in allocating the World Cups were currently in Zurich. These legal actions concern two criminal procedures conducted separately by the OAG and the US Attorney’s Office for the Eastern District of New York. The Swiss and US law enforcement authorities are not conducting any joint investigations, but are coordinating their respective criminal proceedings.
"On 18 November 2014, FIFA had filed criminal charges against persons unknown with the OAG. Therefore, the Swiss proceeding is aimed at persons unknown, with FIFA as the injured party. With this procedure, the OAG is contributing to the struggle against corrupt behaviour and money laundering."Reuse content
