paragraph_text: Second arrest attempt
  
  On 14 January, a military unit assigned to guard the residence's exterior approved the entry of anti-corruption officials and police to arrest Yoon. The Presidential Security Service denied the military unit's approval, stating that it had no authority to allow access to Yoon's residence without the main service's secondary approval.
  
  In the early morning of 15 January, the CIO, with support from the police, made a second attempt to arrest Yoon. The National Police Agency stated that they had organized approximately 1,000 personnel drawn from multiple jurisdictions to execute the arrest warrant. These included 301 detectives from the Seoul Metropolitan Police Agency 's Metropolitan Investigation Unit, 270 personnel from the Gyeonggi Southern Provincial Police Agency with experience in the Anti-Corruption Investigation Unit, the Mobile Criminal Investigation Unit, and the Narcotics Crime Investigation Unit, and additional personnel from the Gyeonggi Northern Provincial Police Agency and Incheon Regional Investigation Units. These personnel would be divided into three groups: the entry team tasked with removing physical barriers and securing access to the presidential residence, the arrest team responsible for apprehending President Yoon, Deputy PSS Chief Kim Sung-ho, and any PSS agents who might resist the operation, and the escort team responsible for safely transporting detained individuals from the scene. Multiple detention facilities were prepared across police stations for resisting security personnel. The operation was planned to be initiated at 5:00 am KST on 15 January, with a long-term dispatch period extending to 17 January. The operation intended to involve mechanical equipment such as cranes and tow trucks for removing physical barriers, riot police deployment for crowd control, and psychological warfare that included loudspeaker announcements offering leniency to cooperating security personnel.
  
  At 4:20 am on 15 January, CIO officials arrived at Yoon's residence. A police line moved towards the residence, broadcasting messages warning that any personnel who obstructed the arrest operation would be arrested. Six layers of physical barricades had been assembled by the PSS outside the residence. About 30 members of the People Power Party along with lawyers Yoon Gap-geun and Kim Hong-il formed a human chain in front of the residence to prevent entry. Yoon Gap-geun called the operation "illegal" and an "internal rebellion". Deputy PSS Chief Kim Sung-ho, who also received an arrest warrant, had his radio communication with other secret service members cut off. Several personnel employed ladders to scale buses that had been positioned as barriers at the entrance, and used bolt cutters to breach barbed wire fortifications. Some officers scaled walls and utilized nearby hiking trails to access the compound from behind the main security buildup.
