This week, it was revealed that the Drug Crime Investigation Unit of the Incheon Metropolitan Police is currently investigating a total of 8 individuals suspected of using illegal drugs at an adult entertainment establishment in Gangnam. 

The investigation unit, which was trailing the whereabouts of a drug packaged that entered Korea via Incheon Port, found that the drugs had been delivered to a Gangnam establishment. Upon the questioning of several employees, the investigation unit obtained the names of the 8 individuals mentioned earlier. They include actor Lee Sun Gyun (48) of 'Parasite' and 'My Mister'; Hwang Hana (35), the granddaughter of 'Namyang Dairy' founder Hong Doo Young; and in the most recent developments, former idol trainee Han Seo Hee (28), who was previously charged with illegal drug use three times, including once in 2016 when she was investigated alongside former Big Bang member T.O.P. 

Furthermore, during the course of this investigation, it was found that actor Lee Sun Gyun paid another individual involved in this case, known as 'A', 350 million KRW (~ $260,000 USD) after being threatened and blackmailed. Lee Sun Gyun's has admitted to this and has since filed a lawsuit against 'A'. 

The Drug Crime Investigation Unit plans on summoning all 8 individuals for questioning and drug testing soon.
