Prosecutors are expected to indict a former vice president of the Osaka Securities Exchange this week in connection with a market manipulation scandal.
Investigative sources said Wednesday the move by the Osaka District Public Prosecutor's Office stems from a formal complaint that the Securities and Exchange Surveillance Commission plans to file against Takuo Noguchi, 66, a former OSE official.
Noguchi will be indicted as early as Thursday but will not be arrested then, they added.
With this step, the OSE scandal -- which led to criminal investigations and undermined public trust in the bourse -- should come to an end.
