  On 11 December 2024, South Korean police raided the Office of the President of the Republic of Korea, with investigators presenting a search warrant specifying Yoon as the suspect. However, the Presidential Security Service refused to cooperate, resulting in a "very limited" number of documents and materials being submitted by Yoon's office. Raids were also conducted on the Defense Counterintelligence Command, the Army Special Warfare Command, the Seoul Metropolitan Police Agency, the National Police Agency, and the National Assembly Security Service. On the same day, the former Defense Minister Kim Yong-hyun attempted to commit suicide at the detention facility while in custody.
  
  On 12 December, the police raided the Joint Chiefs of Staff headquarters adjacent to the presidential compound, as well as the Capital Defense Command headquarters. On 13 December police raided the Gyeonggi Nambu Provincial Police headquarters to investigate the unit's role during martial law. Gyeonggi Nambu Provincial Police had dispatched police forces to the NEC after Yoon's declaration of martial law.
  
  Following his impeachment on 14 December, Yoon confined himself in his presidential residence in Hannam-dong, Yongsan, central Seoul.
  
  On 27 December the National Assembly voted 191–71 to create a special committee to investigate insurrection charges against Yoon, with a tenure lasting until 13 February 2025. The committee was formally opened on 31 December and was composed of 18 lawmakers, including 10 opposition and seven PPP lawmakers and one independent lawmaker.
  
  Yoon was summoned three times by the Corruption Investigation Office for High-ranking Officials (CIO) for questioning on 18 December, 25 December and 29 December over his declaration of martial law. He ignored all three summonses. In response, on 30 December, the CIO filed an arrest warrant for Yoon at the Seoul Western District Court. The warrant was granted by the court the next day. The arrest warrant, valid for seven days up to 6 January 2025, allowed investigators multiple attempts to detain Yoon if initial efforts proved unsuccessful. If detained, the anti-corruption agency would have 48 hours to request a formal arrest warrant, or else have to release him. Yoon's legal team announced their intention to pursue legal action, characterizing the warrant's execution as "illegal and invalid" by asserting that the CIO did not have the authority to issue the warrant.
