The joint investigation headquarters, which is investigating the Dec. 3 martial law incident, sent a summons to President Yoon Seok-yeol, which arrived by registered mail at the official residence in Hannam-dong, Yongsan-gu, Seoul, on the 17th. However, the summons is marked as 'refused recipient' in the postal system. The joint investigation headquarters is a collaborative investigative body consisting of the Korean National Police Agency, the Corruption Investigation Office for High-Ranking Officials (CIO), and the Ministry of National Defense investigation headquarters.
A Korea Post official noted, "At around 9:52 a.m. on this day, mail delivered via vehicle arrived at the residence in Hannam-dong." It is reported that the postman handed over envelopes and boxes after conversing with a representative of the Presidential Security Service.
Concerning this, the joint investigation headquarters stated, "The summons sent to the Presidential Secretariat's Administrative Secretary's Office yesterday is undelivered at present, and the summons sent to the residence is marked 'refused recipient' in the postal system."
Previously, the joint investigation headquarters attempted to deliver a summons to President Yoon by sending investigators to the presidential office and residence the day before, but it was unsuccessful. They explained that while they couldn't deliver it in person, there was no issue with the delivery itself, as the summons was sent to the residence via registered mail.
The joint investigation headquarters is expected to notify President Yoon to appear at the CIO located in the Gwacheon Government Complex at 10 a.m. on the 18th. The summons, prepared under the name of a CIO prosecutor, specifies charges against President Yoon for being the head of a rebellion and obstructing the exercise of authority through abuse of power.
