South Korea's playground for the rich and famous has been rocked by a major scandal over the alleged drugging and rape of young girls, exposing the underbelly of the country's massively popular "K-pop" scene.
Police have arrested more than 350 people in connection with claims of endemic sexual abuse and exploitation in Seoul's Gangnam nightclub district, where K-pop stars mingle with wealthy businessmen and VIPs.
The case has led to intense scrutiny of South Korea's multi-billion-dollar K-pop industry, a global export that was once synonymous with squeaky-clean pop bands but is now facing allegations which resonate with the Weinstein scandal in the US.
Several high-profile K-pop stars, such as singer Seungri, have been dragged into the scandal and interviewed by police, though they strenuously deny any wrongdoing.
According to a BBC investigation, victims were drugged with an undetectable substance known as GHB, before being dragged into nightclub back rooms or alleyways and then raped by one or more men, sometimes while being filmed on mobile phones.
