Carlos Ghosn, the former chief of the Renault and Nissan automakers, currently detained in Japan, will again be charged with breach of trust after his arrest on Monday, local press reported on Friday.
The Tokyo prosecutor's office will put Ghosn under investigation, accusing him of misappropriating Nissan's funds.
He is suspected of using one or more "empty shell" companies to pass on Japanese group funds to an investment firm owned by his son Anthony, according to details given by the NHK public channel quoting a source close to the inquiry.
Kyodo news agency also said that Ghosn will be charged again on Monday.
The investigators now require the cooperation of the US authorities to hear Mr. Ghosn's son, NHK adds.
Trapped for the first time when he arrived on a private jet in Tokyo on November 19, 2018, Carlos Ghosn already faces three counts of compensation and aggravated breach of trust related to an attempt to cover personal financial losses. Nissan.
He had been released on bail on March 6 after 108 days in jail and was placed under house arrest in Tokyo but was arrested again less than a month later for further suspicions.
He and his family deny any wrongdoing and denounce a conspiracy by Nissan as they prepare to merge the Japanese group with their French partner Renault, an evolution of the unpleasant alliance to the Japanese side.
Ghosn's top lawyer, Junichiro Hironaka, has filed several appeals since the arrest of his illustrious client, but the judges rejected them, allowing him to remain in police custody until Monday.
If he is actually charged, he will begin a period of pre-trial detention and, at the same time, open the possibility of an application for bail.
