Greetings!
I am the first Chief Prosecutor Kim Jin-wook of the Corruption Investigation Office for High-ranking Officials(CIO).
Thank you for visiting the website of the CIO.
The CIO is an independent investigative body responsible for investigating crimes committed by high-ranking officials or their family members in relation to their duties. The purpose of the Office is to eradicate crimes by high-ranking officials and enhance transparency in the government and trust in public offices.
The establishment of the CIO is a major change in the constitutional history of Korea as it transformed the criminal justice system of Korea. Prior to its establishment, the Prosecution had monopolized the authority to indict since the foundation of the nation.
As the first Chief Prosecutor of the CIO, I will do my utmost efforts in gaining the trust of the Korean public and for successful establishment of the CIO in the constitutional order of Korea.
Thank you.
The First Chief Prosecutor of the Corruption Investigation Office for High-ranking Officials
