During the course of the investigation, SMPA focused on the Burning Sun club and its affiliates.

Police conducted searches at the Burning Sun club, at the homes of CEO Moon and a sales executive Han, as well as at Burning Sun Entertainment, YG Entertainment, Yuri Holdings, Junwon Industries and Club Arena (and at the Seoul Regional Office of the National Tax Service of South Korea related to allegations of tax evasion).
The investigation found a 2.45 billion won (US$2.15 million) investment to the Burning Sun, with the Taiwanese investor having contributed 1 billion won and Seungri having contributed 225 million won.
Yonhap News Agency reported that one of the club's investors, perhaps Junwon Industries (also called Cheonwon Industry and a major shareholder in Burning Sun Entertainment which operated Burning Sun), Le Méridien Seoul's operator, may have forged a connection with the hotel, in the amount of $8.8 million, using the intermediary firm to attract larger investments to the club.
Junwon CEO Choi Tae-young was charged with embezzling funds, along with Seungri and Yoo.
A Burning sun employee Ahn, who worked as a female Taiwanese investor's Korean guide, was booked for embezzlement charges, and the possibility of any Triad investments or organized crime connections were investigated with Interpol and other agencies.
Burning Sun's female Taiwanese investor Lin was also booked on charges of embezzlement, in collusion with Seungri and Yoo.

Seungri was investigated for allegedly: supplying prostitutes for investors, sharing an illicit photo of a woman in Jung's chatroom, giving concert tickets to a police officer Yoon, and embezzlement of funds from the clubs Monkey Museum and the Burning Sun.
Seungri's business partner and CEO of Yuri Holdings, Yoo In-seok, age 34, was investigated for connections to Gangnam police officer Yoon, embezzling Monkey Museum and the Burning Sun's funds, and for supplying prostitutes, along with Seungri.
 CEO's Lee Sung-hyun and Lee Moon-ho, both age 29, were investigated for allegedly hiring minors as security guards and for bribing former Gangnam police officer Kang with 20 million won (US$17,700) to cover up an underage drinking issue at the club, the latter which Lee Sung-hyun admitted to doing, at a hearing for Kang.
YG head Yang and singer Psy were questioned about additional allegations of sex-for-favors involving Yang and foreign guests Jho Low and Chavanos Rattakul.

Arrests related to Burning Sun included CEO Lee Moon-ho who was detained and charged with drug use and distributing drugs to Burning Sun customers.
Others included a Burning Sun board member Jang, the alleged attacker of clubgoer Kim Sang-kyo, a chat group member named Kim who distributed illicit videos, and a Club Arena security guard Yoon, accused of attacking a guest in 2017.
A Chinese promoter, nicknamed Anna, age 26, was investigaed for drug use and distribution, but no arrest was made.
An owner of Arena, Kang Mo, age 46, and a "puppet head" of the club, surnamed Lin, were arrested on charges of tax evasion, alleged to have not paid taxes in the amount of 16.2 billion won (US$14.31 million) between 2014–2017.
On April 11, SMPA said 59 persons had been apprehended related to drug use and distribution charges in the Burning Sun scandal, and 11 were under arrest.

Former Gangnam police officer Kang, age 44, was arrested for allegations of brokering between the Burning Sun and other police officers, and booked for assisting with an underage drinking incident at the Burning Sun, which co-CEO Lee Sung-hyun admitted to paying him for.
Police firings and investigations included a senior superintendent Yoon, who knew Yoo, and assisted with the underage drinking incident and Monkey Museum's business zoning violations, and was charged with violating the Improper Solicitation and Graft Act for receiving concert tickets from Seungri.

In peripheral investigations, police announced over 500 drug related arrests on March 25, 2019, after declaring "total war" against drug crime on February 25, due to the scandal at the Burning Sun.
