The CEO of luxury automaker Audi has been arrested in Germany as part of an investigation into emissions cheating.

Munich prosecutors said Monday that Rupert Stadler, who has worked for Audi parent company Volkswagen since 1990, had been detained because of concerns he could influence witnesses in an ongoing fraud investigation.

Stadler, 55, is the highest ranking Volkswagen executive to be arrested in connection to a costly diesel emissions scandal that burst into public view in 2015.
