Goo Hara, the Korean pop singer best known for her work in the K-pop girl group Kara, was found dead Sunday at her home in Seoul, the BBC reported. She was 28.
Authorities said the cause of death was still under investigation. The performer, who debuted with the five-member Kara in 2008, had appeared in a series of comeback performances last week following her hospitalization in May after a suspected suicide attempt.
The young star and outspoken advocate against cyberbullying in June said she said she was struggling to overcome depression and pleaded for positive comment on social media, Reuters reported.
In her final Instagram post, sent Saturday to her 1.5 million followers, she showed a selfie in bed with the caption “Good night.”
Goo’s work with Kara was part of the wave of K-pop acts that led to worldwide popularity for the music genre. She also performed as a solo artist, with a 2015 EP that hit No. 4 on the Korean charts and a new single, “Midnight Queen,” released earlier this month.
Goo’s death comes one month after the death of Sulli, a former member of the K-pop girl group f(x) in a suspected suicide. Sulli was a close friend of Goo’s and had also spoken out against cyberbullying.
