Audi CEO Rupert Stadler arrested in diesel emissions probe

German authorities have arrested Audi CEO Rupert Stadler on Monday for his alleged role in the Volkswagen Group's 2015 diesel emissions scandal. Munich prosecutors, who raided Stadler's private apartment last week, said he was arrested over risk that he may tamper with evidence. Stadler has been the luxury carmaker's CEO since 2007 and a Volkswagen Group board member since 2010.
