Senior Superintendent Yun Kyu-geun, widely known as the so-called "Burning Sun police chief," is said to have taken honorary retirement with about a year left before the mandatory retirement age.
According to police and others on the 2nd, Senior Superintendent Yun, who had been serving as Team 1 leader at the 112 Integrated Situation Room at the Gyeonggi Northern Police Agency, took honorary retirement effective on the 31st. Although he had about a year left before reaching the rank-based retirement age, he reportedly retired of his own accord.
Yun became a figure of suspicion for collusion after it was revealed during the 2019 probe into the Burning Sun nightclub scandal that entertainers, including singer Seungri (legal name Lee Seung-hyun), referred to him as the "police chief" in a KakaoTalk chatroom.
Yun was later brought to trial on charges that, during the investigation, he used nonpublic information received from a former CEO surnamed Jeong of the KOSDAQ-listed company Cubes (now Nokwon CNI) to trade stocks and instructed Jeong to delete mobile phone messages.
In September 2021, the Supreme Court finalized a ruling that found parts of the charges—violations of the Financial Investment Services and Capital Markets Act and instigating the destruction of evidence—guilty, upholding a lower court's fine of 20 million won for Yun. The Korean National Police Agency imposed a three-month suspension on Yun the same year.
