Authorities in Switzerland have launched a new wave of house searches as part of their investigation into corruption in world football.
The investigation comes after claims that German football officials paid for votes, in order to host the 2006 World Cup.
It is alleged by German newspaper Der Spiegel that the German bidding committee set up a slush fund that was filled secretly by former Adidas CEO Robert Louis-Dreyfus.
The newspaper claims the amount of money channelled into the slush fund totalled 10.3 million Swiss francs (£8.2 million)
In September it was reported that those involved are suspected of fraud, money laundering, criminal mismanagement and misappropriation. Authorities have now added FIFA General Secretary Urs Linsi to their list of suspects.
A statement from the Office of the Attorney General said: "The Office of the Attorney General (OAG) of Switzerland confirms that on 23 November 2016 it conducted house searches with the support of the Federal Office of Police (fedpol) at various locations in the German-speaking part of Switzerland.
"The measures were carried out as part of the investigations relating to a payment of €6.7 million (£5.68 million) made in April 2005 by the German Football Association (Deutscher Fussball-Bund, DFB) to Robert Louis-Dreyfus."
The German World Cup bid committee denied any wrongdoing following the Der Spiegel report. Responding to the allegations that a slush fund had been used to manouevre money, German Football Association president Wolfgang Niersbach said “I can rule that out categorically.
"I can assure that in relation to the bidding and awarding of the 2006 World Cup there were no ’slush funds’ at the DFB, the bidding committee or the later organising committee.“
