Saburo Sato, a former top aide of ex-Lower House lawmaker Koichi Kato, was served a fresh arrest warrant Tuesday on suspicion of failing to declare 150 million yen that he received from talent agency Rising Production Co., investigative sources said.

Investigators from the Tokyo District Public District Prosecutor's Office believe Sato, 61, thus evaded income tax payments of around 74 million yen, the sources said.

Until January, Sato served as chief accountant of a fund management body for Kato, a former heavyweight of the Liberal Democratic Party who resigned from the House of Representatives in early April to take responsibility for Sato's suspected misconduct.
