Prosecutors on Friday searched UFJ Bank's Tokyo headquarters and the homes of some of its former executives in connection with the bank's alleged obstruction of inspections by the Financial Services Agency last fall.

The FSA filed a criminal complaint against the bank and three of its former executives Thursday over the alleged obstruction with the Tokyo District Public Prosecutor's Office.

Among the places searched was the home of former UFJ Bank Vice President Kazuyoshi Okazaki, although he has not had a criminal complaint filed against him.
