Criminal complaints have been filed against the former deputy head of the Fukuoka District Public Prosecutor's Office for allegedly leaking information to a Fukuoka High Court judge about a police investigation into his wife, Justice Minister Masahiko Komura said Friday.

The complaints have been accepted by Fukuoka district prosecutors and Fukuoka Prefectural Police, Komura said.

The complaints said the actions of Eiju Yamashita, 51, may have violated the National Public Service Law, which stipulates that civil servants must not divulge secrets they have learned through their duties, according to the minister. He added that a criminal probe will now begin.
