Impeached South Korean President Yoon Suk Yeol was in court for the first time Saturday for a crucial hearing that will decide whether to extend his detention as investigators probe his failed martial law bid.

Seoul, South Korea – South Korea’s impeached President Yoon Suk Yeol was formally arrested early Sunday, days after being apprehended at his presidential compound in Seoul. He faces possible imprisonment over his ill-fated declaration of martial law last month.

A South Korean court extended the detention of impeached President Yoon Suk-yeol on Sunday over concerns he could destroy evidence linked to his martial law declaration, enraging his supporters, who attacked the court building.

Despite the public’s support for impeaching the South Korean president, the ruling People Power Party just outpolled the main opposition Democratic Party.

Yoon’s detention, after a tense standoff outside the presidential residence, marks the latest chapter in a bewildering series of events since his martial law decree.
