K-pop under scrutiny over 'toxic fandom' after death of Sulli

Anger grows at culture of exploitation and failure of agencies to protect performers

The death this week of the South Korean singer and actor Sulli has turned the spotlight on the darkest corners of the highly pressurised K-pop industry and sparked anger over the failure of management agencies to protect their stars from the menace of "toxic fandom".

Sulli, a former member of the group f(x), had spoken publicly about her mental health problems and shock at her death has led to calls for greater support for performers. Authorities said she was suffering from severe depression and are investigating suicide as a possible cause of death.
