FRANKFURT — German prosecutors on Tuesday filed charges against six Volkswagen employees for their role in the automaker’s emissions-cheating scandal.

Prosecutors in Brunswick, Germany, accused the unnamed employees of fraud and false advertising as well as tax evasion, since VW cars equipped with illegal emissions-cheating software should not have received road worthiness certification and tax breaks.

The employees worked at the automaker between 2006 and 2015 and were below management board level, prosecutor Klaus Ziehe said, adding it was unclear whether they are still employed at the automaker.

Volkswagen declined to comment.
