The defense team for Carlos Ghosn says the businessman’s latest arrest was illegal and that it interrupted his care for chronic kidney failure.

Reuters reports that documents prepared by Ghosn’s defense team, led by lawyer Junichiro Hironaka, claim that prosecutors in Tokyo, Japan re-arrested Ghosn on April in an attempt to interrupt the defense’s preparation and force a confession.

In these documents, the defense also stated that Ghosn suffers from high cholesterol, chronic kidney failure, and rhabdomyolysis and that interrupting his treatment is “inhuman.”

Prosecutors in Japan re-arrested Ghosn on suspicion of enriching himself at a cost of $5 million to Nissan. Ghosn is currently being held in the same detention center where he previously spent more than 100 days after his initial arrest in 2018. Ghosn was released on $9 million bail for 30 days before his most recent arrest.

A source with alleged information on the conditions of Ghosn’s detention claims that he is being questioned by prosecutors for as much as 14 hours a day and sometimes in the middle of the night.

In a video released last week, Ghosn said that he was innocent.

“This is not about greed or dictatorship, this is about a plot, this is about a conspiracy, this is about backstabbing. I am innocent of all the charges that have been brought against me.”

Ghosn believes there was a plot to oust him as chief executive of Nissan and Renault due to fears that he would integrate the two companies on a deeper level.

“There was fear that the next step of the alliance in terms of convergence and in terms of moving toward a merger, would in a certain way threaten some people or eventually threaten the autonomy of Nissan,” he said.
