FRANKFURT -- German prosecutors searched Porsche's offices on Wednesday as part of an ongoing probe into suspected diesel-emissions rigging, German weekly Der Spiegel reported on Friday.
Three offices and three private apartments belonging to Porsche employees were searched as part of an investigation into their role in an emissions cheating scandal, Spiegel said.
Prosecutors have widened their probe and are now investigating seven current and former Porsche employees, up from four employees, the report said.
Porsche was caught to up in parent Volkswagen Group's emissions-cheating scandal after it used Audi-developed engines with software manipulated to cheat pollution tests.
Porsche had no immediate comment.
