SEOUL, South Korea (AP) — South Korea’s previous defense minister was stopped from attempting suicide while in detention over last week’s martial law, officials said, as police were reported to be raiding President Yoon Suk Yeol’s office Wednesday in their intensifying investigation.

The main liberal opposition Democratic Party also plans to submit a new motion to impeach Yoon for his Dec. 3 declaration that imposed martial law.

Yoon’s ill-conceived power grab has paralyzed South Korean politics, frozen its foreign policy, and rattled financial markets, greatly reducing his chances of completing his five-year term and casting a turbulent shadow over one of Asia’s most robust democracies.

Shin Yong Hae, commissioner general of of the Korea Correctional Service, told lawmakers Wednesday that Kim tried to kill himself at a detention center in Seoul. He said that Kim’s suicide attempt failed after center officials stopped him and that he is in a stable condition now.

At the same parliament committee meeting, Justice Minister Park Sung Jae confirmed Kim’s failed suicide attempt.
