Japanese prosecutors today re-arrested Nissan's sacked chairman Carlos Ghosn on fresh allegations of making Nissan shoulder $16.6m in personal investment losses.
The move dashes chances that he would be released on bail imminently.
Prosecutors also raided Ghosn's residence in Tokyo today in search of evidence, broadcaster TV Asahi reported.
The latest twist in a saga that has jolted the global car industry and Nissan's alliance with France's Renault came a day after a Tokyo court unexpectedly rejected prosecutors' request to extend Ghosn's detention.
That rejection had raised the possibility that the prominent businessman could go free on bail as early as today.
The re-arrest, however, means he could be detained for at least another 10 days in a Tokyo jail, where he has been confined since he was arrested last month on initial allegations of financial misconduct.
The Tokyo prosecutor said the fresh arrest was based on suspicions that around October 2008, Ghosn shifted personal trades to Nissan to make it responsible for 1.85 billion yen ($16.6m) in appraisal losses, and inflicted damage on Nissan by having it deposit a total of $14.7m on four occasions between June 2009 and March 2012 into a related bank account.
The Tokyo court said in a statement today that the lawyer for Ghosn's former deputy Greg Kelly, who was arrested along with Ghosn, has requested his client's release.
Kelly's detention extension was rejected along with Ghosn's.
The dramatic turn of events came hours after Ghosn, through his lawyer and quoted by Japanese public broadcaster NHK, vowed to restore his good name in court and to hold a news conference after his release.
"Things as they stand are absolutely unacceptable," he was quoted as saying. "I want to have my position heard and restore my honour in court."
Television camera crews had gathered outside the Tokyo jail this morning in hopes of catching sight of Ghosn being released.
He was initially arrested on November 19 for allegedly understating his income by about half over a five-year period from 2010. He was later re-arrested for a similar alleged crime covering the past three years.
The maximum penalty for both understating compensation and the latest accusation - aggravated breach of trust - is up to 10 years in prison and/or a fine of 10 million yen.
Nissan said after his arrest that it unearthed multiple instances of possible wrongdoing in an internal investigation triggered by a whistleblower.
The internal probe is ongoing, and has included allegations of diverting company funds to pay for personal expenses.
Sources have told Reuters that investigators have been looking into the use of an internal "CEO Reserve" fund and the role of overseas subsidiaries in alleged financial misconduct.
The Ghosn case has put Japan's criminal justice system under international scrutiny and sparked criticism for some of its practices.
These included keeping suspects in detention for long periods and prohibiting defence lawyers from being present during interrogations, which can last eight hours a day.
The case also marked a dramatic fall for the leader of the Nissan-Renault-Mitsubishi alliance who was once hailed for rescuing Nissan from the brink of bankruptcy.
Nissan chief executive Hiroto Saikawa has since called for changes to weaken the clout of controlling shareholder Renault.
Documents seen by Reuters showed that some discussions about compensating Ghosn out of the public eye were not confined to Nissan, but also included Renault executives.
While Nissan ousted Ghosn from his role as chairman shortly after the initial arrest, Renault has so far not replaced him.
A Nissan spokesman declined to comment on the re-arrest, saying only that the internal investigation was ongoing and expanding into new areas.
Renault also declined to comment.
