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.

Hundreds of South Koreans, bundled up against freezing temperatures and snow, rallied overnight into Sunday near the residence of impeached President Yoon Suk Yeol as authorities prepared to renew their efforts to detain him over his short-lived martial law decree.
