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 embattled leader.

South Korean authorities have granted a request to extend a warrant to detain the country’s suspended President Yoon Suk Yeol for questioning over his surprise declaration of martial law last month.

By Joyce Zhou, Minwoo Park and Eduardo Baptista SEOUL (Reuters) -As impeached South Korean President Yoon Suk Yeol fights for his political survival, the embattled leader has found an ally among young conservative men.

South Korea’s anti-corruption agency says it has received a new court warrant to detain impeached President Yoon Suk Yeol after its previous attempt was blocked by the presidential security service last week.

Lawyers of impeached South Korean President Yoon Suk Yeol and the Corruption Investigation Office for High-Ranking Officials (CIO) probing his short-lived martial law decree on Dec. 3 are at odds over whether the CIO has the authority to arrest and pursue criminal charges against him.

Yoon has been lying low at his official residence in Hannam-dong, an upscale district popular with business tycoons and celebrities known as Korea's Beverly Hills. Meanwhile, investigators seeking to question him on allegations of insurrection have struggled to execute a warrant for his arrest.

South Korea’s impeached leader is barricaded in his Seoul residence, protected by a blockade of buses, barbed wire, crowds of supporters and his own armed security guards. The question now is whether investigators can arrest him without a violent confrontation.
