Long the target of abusive online comments, K-pop star Sulli was found dead at her home yesterday.
The body of the former member of top girl group f(x) was discovered by her manager at her home in the outskirts of Seoul.
Police revealed the 25-year-old had been suffering from "severe depression," adding: "Her manager visited her home after failing to reach her since their last call the night before."
The exact cause of her death is still under investigation.
Police said that there were no signs of foul play and that they did not find a suicide note. Security camera footage at Sulli's home showed no signs of an intrusion.
Sulli, whose real name was Choi Jin Ri, was known for her outspokenness and drive for women's rights, which she had suffered online bullying and harassment for.
She debuted in 2009 as a member of f(x), which quickly became one of the top K-pop girl groups worldwide.
In 2014, after struggling with cyber-bullying, she suspended her career. A year later, she left the group to focus on her acting projects.
Sulli was active on social media and recently hosted a TV series where celebrities discussed their experiences with online abuse.
Her death sent shockwaves through the K-pop fan community.
"I always adored and respected you for your boldness. All I can say is rest in peace," a fan commented on Sulli's Instagram account.
"In heaven, you don't have to act strong or pretend everything is okay," another fan said. "I hope you will only think about yourself there."
