OSAKA (Kyodo) Prosecutors arrested a senior Health, Labor and Welfare Ministry official on Sunday over a case of postal system abuse involving a fabricated ministry document.

The Osaka District Public Prosecutors Office's special investigation squad suspects Atsuko Muraki, 53, director general of the ministry's Equal Employment, Children and Families Bureau, was involved in issuing the document for an organization to enable it to use a mail discount system for the handicapped, according to investigative sources.

She was the head of a ministry section in charge of measures for the disabled when the fabricated document was allegedly issued for the group called Hakusan-kai on May 28, 2004. The document carried the official stamp of the section chief, but there are no materials relating to the issuance of the document in the ministry, the sources said.
