The former Nissan chairman Carlos Ghosn has apparently claimed he'll "tell the truth" during a press conference next week.
Mr Ghosn was arrested in Japan last November.
It came after an internal investigation by the automaker, with the company alleging that he under-reported his income "over many years".
He was also accused of using the business’s money for personal use.
Mr Ghosn has since been charged with financial misconduct and other alleged offences.
He was released on bail of 1 billion yen (€8 million) last month after being detained for more than 100 days.
Today, a tweet posted on a newly-created verified Twitter account under Mr Ghosn's name claimed he was "getting ready to tell the truth about what's happening".
I'm getting ready to tell the truth about what's happening. Press conference on Thursday, April 11.

The account also sent out a Japanese version of the tweet.
According to the Japan Times, it was not immediately clear whether Ghosn himself or a representative was responsible for the tweet.
Mr Ghosn has reportedly been restricted from using the Internet under his bail conditions.
It means he can only use an offline computer at his lawyers' office during weekday working hours.
Prior to his arrest, Mr Ghosn was seen by many commentators as the most powerful executive in the automotive industry.
He oversaw an alliance involving Nissan, Renault and Mitsubishi and led recoveries at all three brands.
Following his arrest, Nissan and Mitsubishi's boards voted to remove Mr Ghosn from his roles.
While he initially remained in his role as Renualt boss, he resigned from the position earlier this year.
