TOKYO, Jan. 10 (Xinhua) -- Japan's securities watchdog filed a complaint against ousted Nissan Motor Co. Chairman Carlos Ghosn and the company itself on Thursday, over suspicions the embattled former chief doctored remuneration reports.

According to the Securities and Exchange Surveillance Commission, both Ghost and Nissan were alleged to have under-reported Ghosn's pay package in the company's securities reports presented to Japanese regulators.

The allegation of the misreporting of remuneration spans a three-year period through last March, said the securities watchdog, which has accused both Ghosn and Nissan of violating Japan's Financial Instruments and Exchange Act.

Ghosn was initially arrested on Nov. 19 last year for allegedly understating about 5 billion yen (45 million dollars) of his 10-billion-yen compensation during the five years through March 2015.

The latest development in the ongoing saga involving Ghosn, detained at the Tokyo Detention House since his arrest in November, comes as the automotive heavyweight has been suffering from a high fever, leading to his interrogation being suspended.

Ghosn's lawyer said Thursday that a doctor attending to the 64-year-old said he has been suffering from a high fever since Wednesday and needed to rest.
