The special investigative squad of the Tokyo District Public Prosecutors Office is investigating the alleged coverup of massive investment losses by Olympus Corp. following the arrests in mid-February of three of its former executives and four former securities firms employees.
It is hoped that investigators will put together a total picture of the scandal by going beyond what the third-party investigatory committee commissioned by Olympus uncovered.
In its report made public in early December, the third-party committee said Olympus began making speculative investments with financial assets in 1985 and that unrealized losses reached nearly ¥100 billion in the last part of the 1990s.
