Audi CEO arrested over 'evidence suppression' risk

Audi CEO, Rupert Stadler, has been detained by German police over matters relating to the (seemingly never-ending) Dieselgate saga. Munich police cited the potential for "evidence suppression" as the reason for his arrest, just a week after he was added to a list of around 20 Volkswagen Group executives being investigated for fraud in relation to the diesel emissions cheating scandal.
