SEOUL - South Korea's former impeached president Yoon Suk-yeol was sentenced to five years in prison on arrest obstruction charges, live footage showed Friday.

The criminal division of the Seoul Central District Court in charge of Yoon's obstruction of justice case handed down the prison sentence to Yoon for abusing the presidential security service to hinder the anti-corruption agency from executing its arrest warrant in January 2025.

The Corruption Investigation Office for High-ranking Officials (CIO) was once thwarted in its attempt to arrest Yoon as the presidential security service formed human shields and bus blockades to prevent investigators from entering the presidential residence.

The team of Cho Eun-suk, an independent counsel who led investigations into Yoon's insurrection and other charges, demanded a 10-year prison term for Yoon.

The court said Yoon privatized the presidential security service for personal safety and private interests by blocking the law enforcement agencies' lawful execution of an arrest warrant and attempting to destroy evidence, pointing out that despite the very bad nature of his crime, he consistently offered unconvincing excuses and showed no remorse.

The court stressed that severe punishment was necessary, considering the need to restore the rule of law damaged by Yoon's crime, but it noted that the fact that he was a first-time offender with no criminal record was considered a favorable factor.

The sentencing, which was broadcast live, was Yoon's first verdict coming from his botched martial law bid.

The first-instance sentencing for Yoon's insurrection charges was scheduled for Feb 19. The special counsel sought a death penalty for Yoon on the charges.

The emergency martial law was declared by Yoon on the night of Dec 3 in 2024, but it was revoked hours later by the National Assembly.

The constitutional court upheld a motion to impeach Yoon last April, officially removing him from office.

The ousted leader was indicted under detention last January as a suspected ringleader of the insurrection, becoming the first sitting president to be arrested and indicted.
