GWACHEON, South Korea (Reuters) – Suspended South Korean President Yoon Suk Yeol did not respond on Wednesday to a second summons by anti-corruption authorities who, along with prosecutors, are investigating his brief martial law decree. which was released earlier this month.

Yoon has not appeared for questioning since 10 a.m. (0100 GMT) on Christmas Day as requested by the Corruption Investigation Office for High-Ranking Officials, after their first summons last week was ignored.

An agency official said it would continue to wait for Yoon on Wednesday, adding that the case should be thoroughly investigated before seeking an arrest warrant, Yonhap news agency reported.

Yoon also did not respond on December 15 to a separate call by prosecutors investigating the declaration of martial law, Yonhap said.

Yoon’s repeated defiance of summons and failures to appear for questioning have sparked criticism and calls from the opposition for his arrest, citing concerns over the potential destruction of evidence.

In a televised speech on December 7, four days after the declaration of martial law, Yoon said he would not shirk legal and political responsibility for his actions.

Yoon was impeached by parliament on December 14 for his short-term imposition of martial law and he must now face a Constitutional Court hearing on whether to remove him from office or restore his presidential powers.

Prosecutors, police and the corruption investigation office have all launched investigations into Yoon and other officials, seeking to pursue charges of insurrection, abuse of power or other crimes.

The insurrection is one of the few cases in which a South Korean president does not have immunity.

A lawyer advising Yoon said he is willing to present his views in person during legal proceedings related to the declaration of martial law.
