BERLIN (REUTERS) - German prosecutors and tax authorities searched offices of the German Football Association (DFB) as well as private homes of current and former officials on suspicion of serious tax evasion, the Frankfurt prosecutors' office said on Wednesday (Oct 7).

It said six unnamed former and current officials of the DFB were suspected of having intentionally falsely declared income from advertising inside soccer stadiums during home games of the national team in 2014 and 2015 as income from asset management, leading to €4.7 million (S$7.5 million) in unpaid taxes.

The DFB, which does not pay taxes for any income from asset management but is obliged to do so for earnings from any commercial activities, did not immediately respond to a Reuters request for comment.

Some 200 officials were deployed in the searches that took place across several locations in five federal states.

"Based on the investigation until now, there is the suspicion that those accused knew of the tax incorrectness but consciously chose it to give DFB a major tax advantage," the prosecutors' office said in a statement.

It did not name the six people nor did it provide any details of their positions within the organisation.

This is the latest in a series of legal cases that have tarnished the DFB. It was also investigated in relation to a suspected misuse of funds in relation to the 2006 World Cup in Germany.

Theo Zwanziger, who headed the DFB from 2006-2012, and his successor Wolfgang Niersbach were investigated for years in Germany and Switzerland over those allegations. Both have denied any wrongdoing.

Reinhard Grindel, who was president from 2016-2019, resigned over a gold watch he received as a gift during a Uefa meeting.
