Former President Yoon Suk-yeol arrived at the comprehensive special prosecutor's office in Gwacheon on Saturday for a second round of questioning [1].

This summons marks a critical escalation in the legal proceedings against the former leader. The investigation focuses on allegations of rebellion, a charge that carries significant political and legal weight in South Korea's democratic framework.

Yoon arrived at the office at approximately 9:40 a.m. [1], traveling in a Ministry of Justice escort vehicle [1]. To avoid public visibility, the vehicle entered the building's underground parking lot directly, meaning the former president's appearance was not seen by the public or press [1].

The second summons is part of a broader effort by the second comprehensive special prosecutor's team to investigate suspicions remaining from three major special probes [2]. The team is currently investigating Yoon as a suspect specifically regarding charges of rebellion [2].

"The special prosecutor is investigating former President Yoon as a suspect on charges of rebellion," a special prosecutor official said [1].

The proceedings in Gwacheon, Gyeonggi Province, continue to be tightly controlled. Reporter Ahn Dong-jun of YTN said the escort vehicle proceeded immediately into the underground garage to ensure the summons remained private [1].

The special prosecutor is investigating former President Yoon as a suspect on charges of rebellion.

The second summons of a former head of state on rebellion charges suggests that the special prosecutor's team believes it has sufficient evidence to move beyond preliminary questioning. By treating Yoon as a suspect rather than a witness, the investigation shifts toward establishing criminal liability for actions that may have threatened the constitutional order.
