K-pop star Sulli has been found dead at her home a month after she sparked controversy in conservative South Korea by accidentally revealing a nipple on Instagram.
Sulli, 25, had previously suffered a huge amount of online abuse in what became known as the 'no-bra' scandal after she repeatedly showed her nipples on social media
It is reported that the pop singer then suspended her music career due to the abuse she had received
Sulli was found by her manager at her home in Seongnam, south of the capital, Seoul at around 3.20pm local time (7.20am UK time).
Korean police said that they are working on the assumption that she may have committed suicide.
Seoul police said in a statement that her manager had tried to call round to the 25-year-old's house last night but received no response.
They added that the K-pop star was battling severe depression and had spoken out against cyber-bullying in the past.
Sulli was known for being controversial and has been slammed on social media since 2016 after she began appearing with no bra on under her top.
She has also appeared drunk during live streams and been criticised for doing so.
Sulli's former f(x) bandmate, Amber Liu, has posted her shock at what's happened.
'Due to recent events I’ll be putting on hold my upcoming activities. Sorry everyone. Thank you for your thoughts,' Liu said on Twitter.
She was close with another K-pop star called Jonghyun who committed suicide aged 27. She paid tribute during his funeral in 2017.
Sulli had been a member of the popular K-pop band F(x) with Liu but left in 2015 to focus on her acting and solo singing career.
In 2017, the star told Grazia that acting allowed her to gain confidence and feel a sense of achievement for her work. She added that she felt it could be a 'lifelong career' for her.
The five-piece girl group she rose to fame in, f(x), officially debuted in 2009 and many consider them to have changed the face of K-pop.
She released four albums with the band before they switched to a four-piece in 2015. Pinocchio (2011), Pink Tape (2013) and Red Light (2014) all featured Sulli.
According to Taylor Glasby, f(x) were instrumental in developing the Girl Crush sub-genre.
Sulli first rose to fame in 2005 when she was 11 for playing Princess Seonhwa of Silla in the SBS drama Ballad of Seodong.
The pop-star turned actress was born in Yangsan, South Gyeongsang, South Korea.
