Lawyers for victims of a massive fraud involving the G.O. investment group plan to sue two broadcasters for airing TV ads featuring the group's president, Genta Ogami, who is now under arrest.

The lawyers, led by Hiroshi Yamaguchi, believe Nippon Television and Asahi National Broadcasting are responsible for exacerbating the damage from the fraud because some of the victims put money in the bogus investment scheme after watching the TV commercials and believing the G.O. group was a trustworthy business.

They plan to take the action against the broadcasters by the end of November.
