SEOUL, Jan 20 – South Korea's impeached President Yoon Suk-yeol has officially entered a new phase of his short-lived administration by becoming the first sitting president to be arrested in the country. He spent his first night at the Seoul Detention Centre after a court approved a detention warrant, a significant development in a nation grappling with political upheaval following Yoon's controversial declaration of martial law on December 3.

Yoon's arrest was part of an investigation into claims of insurrection linked to this announcement. Following his arrest in a predawn operation, he was swiftly transferred to a pre-trial detention, but he could face further consequences as his legal battles unfold. According to Reuters, Yoon underwent a thorough physical examination and had his mugshot taken, standard procedures that apply to all inmates regardless of status.

Yoon was placed in a solitary cell approximately 12 square metres (129 square feet) in size, which differs from the usual accommodation typically allotted to inmates. This facility, located in Uiwang, has previously housed other high-profile detainees, including the former president Park Geun-hye. According to South China Morning Post, his cell is simplified with necessary amenities including a bed, a small table, and a television, albeit with strict viewing time restrictions.

In a legislative session, the Commissioner General of the Korea Correctional Service, Shin Yong-hae, stated that Yoon “cooperated well” during the intake process. The regime he will face as a pre-trial inmate includes rising early for roll call at 6:30 a.m. and lights out by 9 p.m. This environment is designed to be both secure and manageable, considering the high-profile nature of the detainee.

Yoon’s arrest has incited significant public unrest, as hundreds of his supporters clashed with police, leading to several injuries and multiple detentions amid demonstrations demanding his release. Investigators remain focused on Yoon's alleged insurrection for attempting to manipulate legal governance in South Korea, a charge that carries serious penalties, including the potential for lifelong imprisonment. His legal team has challenged the legality of the arrest, arguing over jurisdictional powers and procedural correctness, as Yoon maintains his innocence and promises to battle the accusations.

The socio-political climate remains tense, with Yoon's future uncertain as he navigates the legal landscape and public sentiment. His case highlights the ongoing evolution of accountability for high-ranking political figures in South Korea's turbulent governance.

As investigations continue, the implications of Yoon's presidency, from his controversial decision to declare martial law to his subsequent impeachment, have reignited discussions about political stability and justice in South Korea.
