Investigators arrive at Seoul Detention Center to forcefully escort Yoon for questioning

Thank you for joining us. I'm Yoon Jung-min.

We start our coverage at a local detention center where President Yoon Suk Yeol is being held after a court ordered his formal arrest in the early hours of Sunday.

For more, let's turn to our correspondent Kim Do-yeon standing by live on site.

Do-yeon, I hear the CIO is now trying to bring the president back for questioning by force?

Good evening, Jung-min. Yes, as you said, I'm here at Seoul Detention Center where President Yoon has been under detention since last week and has been refusing to be taken to the CIO for questioning.

As you'll be able to hear, there are some protesters still here showing support for President Yoon.

However, the CIO has now started to take action.

In the afternoon our team spotted what looked like the CIO's vans and cars heading inside and hours later it was confirmed that members of the CIO had indeed arrived.

According to reports there are 6 members of the CIO currently here attempting to escort President Yoon but the option of just holding the questioning session has not been completely ruled out.

President Yoon has only appeared at the CIO once the first day of his detention last Wednesday and has repeated that he's got nothing more to share and refused to be questioned by the investigators.

Of course, Yoon has said that this arrest is not legal yet again and will likely continue to refuse to be questioned and even file for another legality review of this current arrest.

Over the course of this past weekend, the president went from being a temporary detainee to becoming a criminal suspect over insurrection charges.

It almost sounds like a cliche, now, but it is unprecedented.

Jung-min, that's right over the weekend, the CIO was able to get a warrant to keep Yoon in custody until early February.

This second warrant means he is now dressed in a detention center-issued uniform with an inmate number assigned to him.

Considering his status he will have a separate cell, and guards will try to isolate him from other inmates.

According to the Justice Ministry he's had a mug shot taken and a body search the same procedure as anyone else who has been arrested.

The CIO is also using its legal options to pressure President Yoon except for Yoon's attorneys he'll not be allowed any visitors until a formal prosecution begins for this case.

The CIO cited the risk of evidence being destroyed as the reason and remember that is the exact reason why the court issued the second "official" arrest warrant.

Of course, Yoon has called this ban just a way to push him around saying if there is reasonable evidence obtained by the CIO how could he destroy any?

And I believe the police tried to raid some locations related to the President again how'd that go?

Jung-min that's right the search and seizure warrant from last month is still valid and the police attempted to raid the presidential safehouse and Yongsan Presidential Office

The goal was to obtain CCTV footage to see who went in and out on the night of the martial law declaration.

In addition, at Yongsan Presidential Office's Presidential Security Service office the servers for these CCTV recordings are there so the investigators could be looking into those.

However, again the Presidential Security Service refused to comply with the search and the police had to turn back.

That's all for now, back to you Jung-min.

That was our Kim Do-yeon reporting live from the Seoul Detention Center.
