South Korea’s impeached president, Yoon Suk Yeol, was arrested and questioned for hours over his ill-fated declaration of martial law last month, handing himself in after an early-morning standoff outside his official residence in Seoul.

His detention on Wednesday makes him the first sitting president in the country’s history to be arrested.
