The police have released a presidential security official suspected of blocking investigators from arresting President Yoon Suk Yeol.

The special police team handling the martial law case said Sunday that it released Lee Kwang-woo, the head of the Presidential Security Service’s protection bureau, after an investigation. 

Lee was arrested Saturday for alleged obstruction of special official duty in connection with investigators’ attempt to execute their arrest warrant for Yoon. 

The police said in making their decision, they considered the prosecution’s decision not to request a pretrial detention warrant for the secret service agency’s vice chief, Kim Sung-hoon.

Earlier on Sunday the prosecution decided not to seek a pretrial detention warrant for the vice chief, denying a request to do so from the special police team, and the secret service vice chief was immediately released. 

Police plan to investigate further and again request pretrial detention warrants for both secret service officials.
