South Korean President Yoon Suk Yeol has been arrested for questioning, according to the country’s anti corruption agency, in the latest chapter of a weekslong political saga that began with the embattled president’s shock martial law decree last month.

Yoon left his residential compound with investigators in a motorcade Wednesday morning and was taken into custody – the first time such an action has been taken against a sitting president in South Korea.

Yoon is wanted for questioning in multiple investigations related to his short-lived declaration, including over accusations of leading an insurrection – a crime punishable by life imprisonment or even the death penalty.

The embattled president has been holed up in his fortified residence for weeks surrounded by his Presidential Security Service team, evading arrest as he faces several probes and an impeachment trial.
