A gray car arrives in front of the presidential office, and people line up and enter the presidential office's civil service office.

The Emergency Security Joint Investigation Headquarters, set up by the police and high-ranking government officials' criminal investigation offices, visited the presidential office and attempted to submit a request for Yoon Suk Yeol's attendance.

[Son Young-jo / Senior Investigator of Investigation Division 3 of High-ranking Public Officials Crime Investigation Division: 10 p.m. on the 18th, I understand that it was written in the request for attendance at the Senior Civil Servant Corruption Investigations Unit]

However, the presidential office refused to receive the request, saying it was not possible to know whether it was the secretary's job to deliver the suspended president's request for attendance, and the same was true for the presidential residence in Hannam-dong.

However, he explained that there is no problem in delivering the request because the cooperative copy has already sent registered mail.

In the meantime, the special investigation headquarters of the prosecution's emergency martial law also sent a second request for attendance to President Yoon by official letter and mail.

The prosecution also sent a request for attendance on the 11th, but President Yoon reportedly refused to comply with the summons, saying that no lawyers were formed.

While the Joint Chiefs of Staff and the Special Prosecutor's Office are competitively demanding attendance, if President Yoon continues to refuse to summon him, there is even a prospect of arresting the president or attempting to arrest him.

On top of that, the police special investigation team is speeding up its investigation into President Yoon by transferring some of the cases of President Yoon and former Defense Minister Kim Yong-hyun to the Senior Civil Servant Corruption Investigations Unit to expedite procedures such as warrant application.
