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 week’s long 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.

His 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 former prosecutor-turned-politician was stripped of his presidential powers last month after parliament voted to impeach him over the decree.

The country’s Constitutional Court now has the ultimate say over whether he will be formally removed or reinstated.

The Corruption Investigation Office (CIO), which is working with police and the defense ministry to investigate Yoon, first attempted to detain him earlier this month, but it failed in which soldiers and members of the presidential security detail blocked some 80 police and investigators from approaching the presidential compound.

Following his arrest, Yoon released a pre-recorded video message Wednesday in which he again dismissed the investigations into him as “illegal” and said “the law is all broken in this country.”

“As a president who must protect the constitution and legal system of the Republic of Korea, responding to these illegal and invalid procedures is not an acknowledgment of them, but in the hopes of preventing unsavory bloodshed,” he said.
