German police have detained a Porsche manager in a probe into the diesel emissions cheating scandal hanging over the luxury car brand's parent company Volkswagen.
Porsche chief Oliver "Blume informed the workforce that the prosecutor of Stuttgart has taken a manager into custody", a spokesman for Porsche told AFP on Friday.
Porsche did not name the suspect, but Germany's top-selling newspaper Bild and economic weekly Wirtschaftswoche reported that the man held is Joerg Kerner, an engineer in charge of Porsche's engine division and who was working at Audi when the diesel scandal broke in 2015.
Confirmation of the arrest came two days after German police raided offices of Porsche and Audi as part of a fraud probe against three individuals -- two top Porsche executives and a former employee of the luxury carmaker.
The three unnamed individuals are under investigation for suspected fraud and false advertising stemming from the manipulation of exhaust treatment in diesel vehicles manufactured by Porsche.
Both high-end carmakers are owned by Volkswagen, which admitted in 2015 to using cheating software designed to dupe pollution tests in some 11 million cars worldwide, mainly in its own-brand VW cars but also in those made by Audi, Porsche, Skoda and Seat.
