Nissan chief Ghosn arrested over financial misconduct: reports

Nissan chairman Carlos Ghosn was reportedly under arrest in Tokyo on Monday, as his firm accused him of "significant acts of misconduct" and said it would seek to oust him.

Japan's public broadcaster NHK and other media outlets said Ghosn had been arrested after being questioned by Japanese prosecutors for various improprieties including underreporting his income.

"The Tokyo District Public Prosecutor's Office arrested Nissan chairman Ghosn on suspicion of violation of the Financial Instruments and Exchange Act," NHK said.

In a statement, Nissan said it had been conducting a probe into Ghosn for several months after receiving a whistleblower report and had uncovered misconduct going back several years.

The Tokyo prosecutor's office had no comment on the reports about Ghosn, who also heads an alliance of Renault, Nissan and Mitsubishi.

Nissan said it had launched an investigation into both Ghosn and Representative Director Greg Kelly several months ago.

"The investigation showed that over many years both Ghosn and Kelly have been reporting compensation amounts in the Tokyo Stock Exchange securities report that were less than the actual amount, in order to reduce the disclosed amount of Carlos Ghosn's compensation," the statement said. "Also, in regards to Ghosn, numerous other significant acts of misconduct have been uncovered, such as personal use of company assets, and Kelly's deep involvement has also been confirmed."
