German authorities have detained the chief executive of Volkswagen’s Audi division, Rupert Stadler, as part of a probe into the manipulation of emissions controls.
The dpa news agency said Volkswagen confirmed reports that Mr Stadler was detained on Monday.
A total of 20 people are under suspicion in the probe.
The probe of Mr Stadler focuses on cars sold in Europe that were believed to be equipped with software which turned emissions controls off during regular driving.
Volkswagen has pleaded guilty to criminal charges in the United States. Two managers are serving prison terms in the United States.
