Ousted Nissan Motor Co. Chairman Carlos Ghosn has had a high fever since Wednesday evening and his interrogation has been suspended as a doctor said he needs rest, one of his lawyers said Thursday.

Ghosn, 64, who has been detained at the Tokyo Detention House since his arrest in November, made his first public appearance on Tuesday when he attended an open court hearing to seek an explanation for his prolonged detention and declared his innocence regarding financial misconduct and other allegations.

The Tokyo District Court on Wednesday dismissed his lawyers' request to end the detention and also rejected on Thursday their complaint filed against the decision.

Ghosn and his close aide Greg Kelly were initially arrested on Nov. 19 on suspicion of understating the former chairman's 10 billion yen remuneration by roughly 5 billion yen in Nissan's securities reports during the five years through March 2015.

The two were charged on Dec. 10 and served with fresh arrest warrants for similar alleged misconduct during the three years through March 2018.

Ghosn's detention was further extended after he was served with a third arrest warrant on Dec. 21 for alleged aggravated breach of trust involving the transfer of personal investment losses to Nissan in 2008.

His defense team said he could remain in detention for at least another six months as a court rarely grants bail before a trial begins and because Ghosn denies the allegations completely.

Japanese prosecutors are likely to indict him Friday, when his current detention period expires for the alleged breach of trust.
