SEOUL — South Korea's impeached President Yoon Suk-yeol faces a new and potentially more robust attempt to arrest him for insurrection after a top investigator vowed to do whatever it takes to break a security blockade and take in the impeached leader.

With a warrant out for his arrest, South Korea president Yoon Suk Yeol has hunkered down in his hillside villa for weeks. Investigators failed to detain him Jan. 3. As they prepare a new attempt, presidential guards are fortifying the residence.

Crowds of people wrapped up against the bitter January cold clutch signs emblazoned with the slogan “Stop the Steal,” wave US flags, and don red MAGA-like hats.
