Seoul: The state anti-corruption agency faced a setback on Monday when it failed to forcibly bring in impeached President Yoon Suk Yeol for questioning regarding his involvement in a botched martial law bid. This incident unfolded at the Seoul Detention Center, where investigators from the Corruption Investigation Office for High-ranking Officials (CIO) withdrew after a six-hour standoff, vowing to make another attempt later.

According to Yonhap News Agency, the CIO's efforts to "detain and question the suspect" were thwarted by Yoon's persistent refusal to cooperate with the investigation. The agency cited human rights protection regulations as the reason for suspending the attempt. Earlier, six investigators were dispatched to the detention center to forcibly question Yoon, who had been formally arrested on Sunday after ignoring repeated orders to appear for questioning.

The CIO had previously indicated that it was "strongly considering bringing him in by force" due to his non-cooperation, emphasizing that such measures are legally permissible and supported by court precedents. Yoon is expected to remain in custody until January 28, with the possibility of an extension to February 7 if granted by the court.

The agency plans to continue discussions with the prosecution regarding the transfer of the case for further investigation and potential indictment. Yoon is facing charges of leading an insurrection and abusing his power during a short-lived imposition of martial law on December 3. His arrest followed the issuance of a court warrant, which was prompted by concerns over potential evidence tampering.

The warrant's issuance sparked protests, with large numbers of Yoon's supporters storming the court, resulting in injuries to police officers and damage to the building. The CIO has indicated that it will seek police cooperation to ensure the safety of investigators involved in probing the case.
