Nissan's former chairman Carlos Ghosn has been indicted by Tokyo prosecutors, along with the company itself.
That's according to Japanese state media on Monday (December 10), the same day Ghosn's 22 day detention period came to an end.
He had been held without charge following his arrest last month, suspected of under-reporting his compensation for years.
Media reports say Nissan itself was indicted for making false statements in annual reports.
Sources have told Reuters that there are concerns in the company that CEO Hiroto Saikawa might be indicted as well.
Analysts have said it would be difficult for Nissan to avoid blame, whether it turns out that other executives knew about Ghosn's misconduct or that the company lacked adequate internal controls.
Lately Nissan's stepped up its offensive against Ghosn, the executive once credited for rescuing the company from near bankruptcy.
On Sunday (December 9) it said it was seeking to block access by Ghosn's representatives to an apartment in Rio de Janeiro, saying he might remove or destroy evidence.
Its also blamed Ghosn for a series of infractions, including personal use of company funds.
Ghosn was arrested late November on suspicion of understating his pay, reporting about half the actual $88 million over a period of five years.
Nissan says he did so with the help of former Representative Director Greg Kelly, who was indicted Monday as well.
