Japanese prosecutors arrested former Nissan Motor ChairmanCarlos Ghosn for a fourth time on Thursday.
They alleged he had tried to enrich himself at the automaker’s expense.
Carlos Ghosn denied charges against him and called on the French government for help.
His wife Carole Ghosn said in an interview the French government should do more for him, as a French citizen, it’s his right.
The prosecutors suspected Ghosn made payments through a company where his wife is an executive to purchase a yacht and a boat.
Under Japanese law, Ghosn could be held without charging for up to 22 days.
France holds a 15 percent share in Nissan’s alliance partner Renault.
A French official said the situation was being monitored.
The French ambassador is in regular contact with him.
