BERLIN -- German prosecutors investigating the Volkswagen Group diesel-rigging scandal have expanded the criminal fraud probe by adding another suspect, bring the total number of people under investigation to 38.
Prosecutors, who are conducting three related probes, have steadily increased the list of suspects, adding former CEO Martin Winterkorn to the fraud investigation in January.
Prosecutors in Brunswick in VW's home state are handling the central investigation in Germany while their Munich colleagues started looking into the company’s Audi unit in March and the Stuttgart prosecutors’ office did the same with the Porsche brand in July.
Klaus Ziehe, a spokesman for the law-enforcement agency, declined to identify the new suspect or comment on the suspect's role at the company.
VW spokesman Eric Felber declined to comment.
VW faces an increasing number of probes at home and abroad after it admitted in September 2015 that about 11 million diesel vehicles worldwide were sold with so-called defeat devices.
