TOKYO -- Japanese investigators, in an unfolding scandal involving major broker SMBC Nikko Securities, are looking into the possibility that several departments may have taken part in suspected market manipulation practices, informed sources told Nikkei on Tuesday.
By Tuesday, prosecutors at the Tokyo District Public Prosecutors Office questioned senior officials at the company, as they tried to uncover the scandal in collaboration with the Securities and Exchange Surveillance Commission, a key market regulator. The prosecutors are investigating the case as a potential violation of the Financial Instruments and Exchange Act, which governs market practice.
