BERLIN (REUTERS) - German prosecutors have charged three former German Football Association (DFB) officials and one Swiss former official from world football's governing body Fifa with serious tax evasion in connection with the 2006 World Cup, which Germany hosted.

In a statement on Friday (June 1), the Frankfurt prosecutor's office said it has also filed a request to involve the DFB in the criminal proceedings which could lead to fines.

The office did not name the four officials but said they were aged between 67 and 76 years.

The three senior DFB officials are accused of arranging for incorrect tax returns to be submitted for 2006 to enable the association to avoid paying around €13.7 million (S$21.4 million) in taxes, the office said.

The tax return included a €6.7 million payment from the DFB to Fifa for a World Cup event, although the funds were in fact used for another purpose and should not have been offset against tax, it said.

The DFB and Fifa could not immediately be reached for comment.

The payment in question has triggered several investigations in the past two years over allegations it had been used as a slush fund to buy votes in favour of Germany's bid to host the 2006 tournament.

A DFB-commissioned investigation in 2016 said the sum was the return of a loan via Fifa from former adidas chief Robert Louis-Dreyfus.

Last October, the tax office ordered the DFB to pay €19.2 million in back taxes related to the payment for the 2006 World Cup.
