With the arrest warrant for impeached President Yoon Suk Yeol expiring on Monday, the South Korean anti-corruption agency asked police to detain the embattled leader.

The Corruption Investigation Office for High-ranking Officials will likely seek a new court warrant to extend the window for Yoon’s detention, according to police.

Dozens of anti-corruption agency investigators and assisting police officers attempted to detain the impeached president on Friday but retreated from his residence in Seoul after a tense five-hour standoff with the presidential security service.
