South Korea's impeached president spends first night in jail

South Korea's impeached President Yoon Suk Yeol had his mug shot taken and underwent a physical check before spending his first night in jail as a criminal suspect, a prison officer said on Monday.

Yoon was arrested in a dawn raid last week, becoming the first sitting South Korean head of state to be detained in a criminal probe on insurrection charges over his botched declaration of martial law.

South Korea was plunged into political chaos by Yoon's December 3 martial law declaration, which lasted just six hours before lawmakers voted it down. They later impeached him, stripping him of his duties.
