Automaker Nissan has broadened its investigation into former chairman Carlos Ghosn to include dealings that took place in the U.S. India and Latin America.
That's according to three Reuters sources with knowledge of the inquiry.
In one part of the probe the company is looking into calls made in the U.S. by Jose Munoz, who led Nissan's North American operations for four years up to 2018.
Reuters sources said Munoz, who's considered within the industry as close to Ghosn, had been quote "stonewalling" the investigation.
One of the sources described him as a person of interest in the probe but also said it wasn't clear if Munoz would actually be accused of any wrongdoing.
And on Saturday (January 12) a Nissan spokesperson confirmed that Munoz had resigned from the firm where he had currently been heading up Nissan's China operations.
Munoz did not reply to Reuters request for comment, and one of Ghosn's legal team members said in an emailed comment that they were unaware of the matter.
One source told Reuters that some of the questions put to Munoz relate to dealer franchise rights and others relate to contracts with parts and service suppliers that he approved when running Nissan's U.S. operations.
Reuters also understands Nissan's probe is looking into Ghosn's role in calls on dealer franchise decisions in other countries including India.
And the possibility of outsized payments for bodyguard services in Brazil.
Before his arrest in November Ghosn was one of the most celebrated executives in the auto industry widely credited with saving Nissan from bankruptcy.
Ghosn has been charged with underreporting his income.
And on Friday (January 11) was also indicted on aggravated breach of trust over allegedly shifting investment losses to Nissan temporarily.
On Tuesday (January 8) Ghosn made his first public appearance since his arrest in a Tokyo court where he declared his innocence and said he had never received any undisclosed income.
