The Corruption Investigation Office for High-ranking Officials(CIO) has resumed its search and seizure for evidence after an indictment notice against the head of the Seoul High Prosecutors' Office was leaked.

CIO investigators continued their search at the information and communications unit of the Supreme Prosecutors' Office(SPO) Monday morning, after launching the raid last Friday. A total of seven prosecutors and investigators are subject to the raid.

The CIO suspects that the indictment against Seoul High Prosecutors' Office chief Lee Sung-yoon, who is accused of exercising undue influence over an investigation involving an alleged illegal travel ban on former Vice Justice Minister Kim Hak-ui, was leaked on duty.

Two of the prosecutors affected by the raid claimed that the CIO's warrant contains false information. They plan to file a complaint against the CIO for creating a false public document.
