South Korean investigators attempting to execute a warrant to detain impeached President Yoon Suk Yeol over his failed martial law bid were locked in a standoff with the Presidential Security Service (PSS) outside the presidential residence Friday, Yonhap News Agency reported.

Investigators with the Corruption Investigation Office for High-ranking Officials (CIO) presented warrants to detain Yoon and search the residence, but PSS chief Park Chong-jun denied their entry, citing restrictions on secured areas.
