South Korea’s president is behind bars

After defying government investigators for weeks, Yoon Suk Yeol became South Korea’s first sitting president to be placed under arrest. Around 1,000 security officers moved in on the president’s official residence in the early hours of Wednesday. Yoon is being investigated on charges of insurrection, after declaring martial law in early December. He essentially gave himself up today, saying that he would cooperate with investigators in order to prevent bloodshed. But Yoon called the action against him “illegal.” The World’s Matthew Bell is in Seoul and has the latest.
