Volkswagen 'dirty diesels' scandal: Audi CEO Rupert Stadler arrested on risk he may suppress evidence

Frankfurt: Audi chief executive Rupert Stadler has been arrested in connection with parent company Volkswagen's "dieselgate" emissions cheating scandal, German prosecutors said Monday.The dramatic development comes a week after Munich prosecutors raided Stadler's home after charging him with fraud and the falsification of documents that allowed diesel vehicles equipped with cheating software to be sold to European customers.Prosecutors said the arrest was justified because of the "risk of concealment of evidence".Audi confirmed the arrest to AFP, declining to give further details."For Mr Stadler, the presumption of innocence continues to apply," a spokesman said in a statement.[caption id="attachment_4534861" align="alignleft" width="380"]
