Suspended South Korea’s  President Yoon Suk Yeol was released from prison on Saturday, a day after a Seoul court canceled his arrest to allow him to stand trial for rebellion without being physically detained.

Released Yoon was shown in a live broadcast as he walked out of the detention center waving and bowing to supporters who were shouting his name and waving South Korean and U.S. national flags while he climbed into a black van to travel to his residence in Seoul.

In a statement distributed by his lawyers, Yoon said that he “appreciates the courage and decision by the Seoul Central District Court to correct illegality,” while he also thanks his supporters and asked those who are on hunger strike against his impeachment to end it.

Yoon was arrested and indicted by prosecutors in January over his Dec. 3 martial law decree that plunged the country into huge political turmoil.

 The opposition-controlled National Assembly separately voted to impeach him, leading to his suspension from office.

The Constitutional Court has been deliberating whether to formally dismiss or reinstate Yoon.

The Seoul Central District Court said Friday it accepted Yoon’s request to be released from prison, citing the need to address questions over the legality of the investigations on the president.

Yoon’s lawyers have accused the investigative agency that detained him before his formal arrest of lacking legal authority to probe rebellion charges.

The Seoul court also said the legal period of his formal arrest expired before he was indicted.

Yoon’s release came after prosecutors decided not to appeal the decision by the Seoul Central District Court. South Korean law allows prosecutors to continue to hold a suspect while pursuing an appeal, even after his or her arrest is canceled by a court, AP reported
