Tokyo police will establish a criminal case against former Social Democratic Party lawmaker Kiyomi Tsujimoto on suspicion of fraud by skimming government salaries for her policy secretaries, according to investigative sources.

Tsujimoto, 43, who resigned from the House of Representatives when the scandal broke in March 2002, and several other people will be charged with fraud, the sources said.

Investigators from the Metropolitan Police Department have questioned Tsujimoto on several occasions, and have collected relevant documents from the Lower House secretariat as evidence against her, the sources said.
