A district court has approved a second warrant for the detention of impeached South Korean President Yoon Suk-yeol.

This comes after investigators failed to detain him last week. Presidential security personnel blocked them upon entering Yoon's residence and the officers withdrew. The first warrant expired on Monday.

Yoon faces charges of orchestrating an insurrection by declaring a short-lived martial law order almost a month ago. He's stood firm despite the ensuing political turmoil.

Yoon's supporters continue to hold rallies, vowing to protect their president. Local media report security has been beefed up at his residence, meaning investigators could face more trouble executing a warrant.

The head of the anti-corruption body that's part of the joint team seeking Yoon's detention says their next attempt will be their last.
