Seoul, January 19, 2025 – A South Korean court has extended President Yoon Suk Yeol’s detention for up to 20 days amid concerns that he could destroy evidence related to a criminal investigation into his brief declaration of martial law in early December.
Yoon, who was arrested on Wednesday, became the first sitting South Korean president to be taken into custody, facing allegations of insurrection. South Korean investigators requested the extension after Yoon refused to be questioned by authorities. On Friday, the Seoul Western District Court approved the Corruption Investigation Office for High-ranking Officials (CIO)’s request to extend the detention warrant. The court cited concerns that Yoon may destroy evidence related to the case.
The CIO confirmed that Yoon is being held at the Seoul Detention Centre, and they will conduct the investigation in accordance with legal procedures.
After the court’s decision, a group of Yoon supporters broke into the court building around 3 a.m., damaging property, assaulting police officers, and chanting for the president’s release, according to Yonhap News Agency. TV footage showed a large police presence managing the situation.
Earlier on Saturday, Yoon attended court for the first time since his arrest, as his supporters rallied outside, clashing with police and holding signs demanding his release. Sixteen protesters were arrested after attempting to force their way into the building.
Yoon’s December 3 martial law declaration lasted only six hours before it was voted down by lawmakers, despite his order for soldiers to storm parliament and stop the proceedings. He was impeached shortly after the incident.
In response, Yoon sent a letter through his lawyers thanking his supporters, calling their protests an act of “passionate patriotism.”
The court’s decision to approve the detention gives prosecutors time to formalize an indictment against Yoon for insurrection, which could result in a life sentence or execution if he is convicted. Should the indictment proceed, Yoon could remain detained for up to six months during the trial.
Additionally, Yoon is absent from the ongoing Constitutional Court proceedings, where the court is determining whether to uphold his impeachment. If the court rules against him, new elections will be held within 60 days.
