Ex Volkswagen CEO investigated over emissions rigging claims
German prosecutors have opened an investigation of Volkswagen's former CEO on allegations of market manipulation in connection with the company's emissions rigging scandal.
Braunschweig prosecutor's spokesman Matthias Diekman said Martin Winterkorn and one other unidentified VW employee are being investigated on allegations they did not release information about the manipulation in a timely manner.
They opened the investigation at the behest of Germany's Federal Financial Supervisory Authority.
Mr Winterkorn stepped down as the scandal came to light, saying he was doing so "in the interests of the company even though I am not aware of any wrongdoing on my part".
