South Korea’s former defence minister has been formally arrested on insurrection charges related to President Yoon Suk Yeol’s brief declaration of martial law, which plunged the country into chaos, a court spokesperson said early Wednesday. Yoon suspended civilian rule a week ago and sent special forces and helicopters to parliament, before lawmakers forced him to rescind the decree in a country assumed to be a stable democracy. Two top police officials were also taken into custody in the early hours of Wednesday, as the investigation into the political turmoil caused by the martial law declaration gathered pace. Former defence minister Kim Yong-hyun, who had first been detained Sunday, has now been arrested on charges including “engaging in critical duties during an insurrection” and “abuse of authority to obstruct the exercise of rights”. A spokesperson for the Seoul Central District Court told AFP early Wednesday that Kim’s formal arrest came amid concerns that evidence might be destroyed. It was determined that Kim’s alleged offences “fall within the scope of crimes for which the prosecution can initiate an investigation,” the spokesperson said. Kim was contrite Tuesday, saying through his lawyers that “all responsibility for this situation lies solely with me”. He “deeply apologised” to the South Korean people and said that his subordinates were “merely following my orders and fulfilling their assigned duties”. Earlier Tuesday, Army Special Warfare Command chief Kwak Jong-geun told lawmakers that Yoon had ordered him to stop enough MPs from gathering at parliament to vote down the martial law decree. “The president called me directly through a secret line. He mentioned that it appears the quorum has not yet been met and instructed me to quickly break down the door and drag out the people (lawmakers) inside,” Kwak said. Lawmakers passed a motion Tuesday to appoint a special counsel to investigate the martial law case. Yoon’s ruling party said it is forging a “resignation roadmap” that reportedly could see him step down in February or March before fresh elections, while the opposition plans to organise an impeachment vote every Saturday. A day after Yoon was barred from travelling abroad, authorities banned more top officials from leaving the country, including Cho Ji-ho, commissioner general of the Korean National Police Agency, police told AFP. Cho and Kim Bong-sik, the head of the Seoul Metropolitan Police Agency, were arrested early Wednesday without warrant, Yonhap news agency reported. They can be held up to 48 hours for questioning before a formal arrest.
