Details are slowly beginning to trickle out about the alleged misdeeds of the embattled Nissan Chairman Carlos Ghosn, who was arrested this week after the carmaker said he misused company funds for personal use.

Nissan Motor Co. (NSANY.PK) provided Ghosn with six houses, including residences in Tokyo and New York, a company official said, asking not to be identified discussing private information. Media reports had earlier said Ghosn got company-funded properties in cities such as Beirut, Rio de Janeiro, Paris and Amsterdam. Ghosn’s sister also had an advisory contract with Nissan, though the role had no substance, the official said. Media reports said she was paid about $100,000 a year.

Ghosn was arrested Monday for alleged financial irregularities that include under reporting of income and misuse of company funds. Prosecutors said Ghosn may have undeclared income of as much as 5 billion yen (US$44 million). As more details begin to emerge, the actual number may be higher, the official said Thursday.
