• Former South Korean President Yoon Suk Yeol is facing insurrection charges.
• Yoon appeared for questioning by special prosecutor under threat of arrest.
• Legal team claims the investigation is politically motivated.
• Yoon's failed martial law attempt in December shocked the nation.
• A court previously rejected a warrant for Yoon's arrest based on his willingness to cooperate.

Ex-President Yoon Suk Yeol has been summoned for questioning by a special prosecutor amid intensifying investigations into his failed attempt to impose martial law in December. His arrival at the Seoul High Prosecutors Office marks his response to the prosecution following threats of another arrest, as reported by Channel News Asia, South China Morning Post, Anadolu Agency, and Reuters.

Yoon's legal representatives have criticized the special prosecutor's inquiry as a violation of his rights, asserting that the situation is "politically motivated" and "full of falsehood and distortion." They stated that Yoon would respond truthfully to the allegations against him, according to Channel News Asia, South China Morning Post, and Reuters.

The attempt to impose martial law in December was seen as a major shock to South Korea, which has moved away from military dictatorship to establish a democratic society since the 1980s. Following this incident, Yoon was impeached by parliament, a decision later upheld by the Constitutional Court, as reported by Anadolu Agency and South China Morning Post.

Despite previously refusing to respond to multiple summonses, a court rejected the special prosecutor's request for an arrest warrant after Yoon expressed his willingness to cooperate. He is also facing charges for abuse of power linked to the martial law declaration, according to Channel News Asia, Reuters, and South China Morning Post.
