OSAKA -- The Osaka District Public Prosecutor's Office on Monday arrested the head of the Osaka High Prosecutor's Office's public security department on suspicion of fraud and abuse of power concerning the auction of a condominium.

Prosecutors from the district office arrested Tamaki Mitsui, 57, on suspicion of submitting falsified documents on July 24 last year to make it appear he had moved into a condominium in Kobe's Chuo Ward so he could fraudulently obtain documents from the ward office to receive tax breaks.

Shortly before his arrest, Mitsui was relieved of his post and transferred to the general affairs department of the Osaka High Prosecutor's Office to facilitate the arrest and the investigation, senior Justice Ministry officials said.
