President Yoon refuses to answer CIO's questions over imposition of martial law on Dec. 3

The president has been under interrogation by the corruption investigation office since 11 AM this morning.

For more on how the investigation is unfolding, we have our correspondent Choi Min-jung, joining us live from the investigation office in Gwacheon.

Min-jung, let's begin with the details of his arrival at the investigation office.

Right, President Yoon was transferred to the anti-corruption agency's headquarters here in Gwacheon, just twenty minutes after his 10:33 AM arrest at the presidential residence in Hannam-dong.

He left the residence in a convoy of security vehicles.

The Corruption Investigation Office for High-ranking Officials had set up a photo line at the front entrance for President Yoon, but he entered the building through a back door restricting his appearance to journalists waiting outside.

Being escorted in a security vehicle and limiting his exposure to the public was likely a measure taken considering his status as the sitting president.

Now, how is the investigation unfolding?

Right, nine hours have passed since the interrogation began at 11 AM in a video recording room.

From 11 AM to 1:30 PM, deputy chief of the CIO, Lee Jae-seung, conducted the investigation,. with Yoon's legal team present, including Yun Gap-geun.

The interrogation resumed in the afternoon at 2:40 PM, conducted by Senior Prosecutor Lee Dae-hwan.

President Yoon refused to testify during the questioning and exercised his right to remain silent.

And it remains to be seen whether Yoon will cooperate at all, given his stance that the investigation is "illegal."

The anti-corruption agency also mentioned that while President Yoon is currently being questioned in a video recording room, no video is being recorded due to his refusal to be taped.

Yoon is expected to be questioned on multiple allegations tied to the imposition of martial law on December third, including the unlawful declaration and proclamation of martial law, insurrection, abuse of power, sending troops to the National Assembly on the night of the declaration to stop lawmakers from voting down the decree, and attempting to illegally arrest opposition and ruling party leaders.

We have yet to know how long the questioning will last, but the CIO reportedly prepared 2-hundred pages worth of questions for Yoon.

That's all I have for now.

Back to you, Jung-min.
