  In the early morning hours of 3 January, investigators from the CIO, accompanied by police forces, entered Yoon's presidential residence to execute the arrest warrant. The arrest team was reported to have comprised about 150 personnel, with 30 members from the Supreme Prosecutors' Office and 120 from the special police unit. Of these, 80 personnel (30 prosecutors and 50 police officers) entered the residence grounds, while 70 additional police officers remained on standby outside, with some reinforcements arriving later. Yoon had reportedly been isolated since 14 December, following the impeachment proceedings. Extensive barricades and vehicle restrictions were enacted in the Hannam-dong area in advance of the operation.
  
  The operation began around 7:00 am local time. Investigators breached initial security barriers, but were stopped at the residence entrance by Chief of Presidential Security Service Park Jong-jun, who refused access. The Presidential Security Service cited two articles in South Korea's Criminal Procedure Act regarding the protection of official secrets to justify blocking access to investigators. The CIO chief Oh Dong-woon warned that attempts to obstruct Yoon's arrest could result in additional prosecutions. Democratic Party floor leader Park Chan-dae stated that any attempts to obstruct the arrest operation would be charged with complicity in sedition and obstruction of their duties.
  
  At 8:02 am, two bulletproof vehicles reportedly exclusively used by Yoon and the first lady were captured on video leaving his residence. It was later speculated that Yoon fled the premises using these vehicles.
  
  At 9:54 am local time, Yonhap reported that prosecutors had broken through military service units blocking the residence, including the 55th Security Brigade of the Army Defense Command, which maintained the second line of defense. Regular soldiers from the Defense Command had also been deployed to impede the arrest warrant's execution. Multiple members of Yoon's legal team entered his residence, and mounted several legal challenges to the arrest warrant. They argued that the warrant could not be enforced at the presidential residence, citing laws protecting locations containing military secrets from searches without proper consent. The lawyers also questioned the CIO's authority to investigate "rebellion charges" and disputed police officers' legal right to assist in the detention operation.
  
  According to media reports, investigators faced a human wall of approximately 200 presidential personnel and experienced "various small and large scuffles" during their attempt to execute the arrest warrant. The CIO said investigators reached to within 200 meters of Yoon's residential quarters before they were blocked. After roughly six hours of confrontation at Yoon's residence, the CIO suspended their operations. Authorities stated afterwards "We determined that executing the detention warrant would be practically impossible due to the continued confrontation and suspended the execution out of concern for the safety of on-site personnel caused by the resistance."
  
  On 4 January, investigators asked acting president Choi Sang-mok to order the presidential security service to allow Yoon to be arrested.
  
  On 9 January, it was reported that the National Investigation Headquarters would assemble 1,000 officers in the next arrest attempt.
  
  On 10 January, the head of the Presidential Security Service Park Jong-jun resigned. Park had been summoned to the National Investigation Headquarters of the National Police Agency for questioning on charges of obstruction of official duties by preventing the arrest of the impeached president.
