Former Nissan chief Carlos Ghosn was rearrested today in Tokyo on fresh financial misconduct allegations, with the auto tycoon slamming his detention as "outrageous and arbitrary".

Authorities arrested the 65-year-old less than a month after he was dramatically freed on bail after more than 100 days in detention.

This marks the latest twist in a case that has gripped Japan and the business world since November.  

Ghosn was detained at the central Tokyo apartment he has called home since his release on bail, with local media later reporting he had been transferred to the Kosuge detention centre.  

"Why arrest me except to try to break me? I will not be broken," Ghosn said in a statement issued through his representatives. 

"My arrest this morning is outrageous and arbitrary," he added. 

Prosecutors said Ghosn had been detained over transfers of Nissan funds totalling $15m between late 2015 and the middle of 2018. 

They suspect $5m of that amount was used by Ghosn for personal expenditure.

"The suspect was responsible for overseeing the whole of Nissan's operations and performing his duty loyally so as not to cause losses to Nissan, but he betrayed that duty in order to benefit himself," they said in a statement.

But Ghosn's lawyer told reporters that prosecutors were engaging in "hostage justice."

"It's extremely unfair," Junichiro Hironaka told local media. 

Reports emerged this week that Japanese prosecutors were investigating transfers by Ghosn of over $30m of Nissan funds from 2012.

That came after news that Renault, which Ghosn also once headed, had handed French prosecutors documents showing the auto tycoon had authorised suspicious transfers worth million of euros.
