The South Korean police on Monday found the dead body of a former member of top Korean girl group F(x), Choi Jin-Ri popularly known by her stage name of Sulli.

The Police said the corpse of the 25-year-old Sulli who had severally spoken out against cyber bullying was discovered at her home in Seongnam, south of Seoul, the country’s capital.

“Her manager visited her home after failing to reach her since their last call the night before,” the Korean Police said in a statement.

The statement added that Sulli who made her debut with the five-member F(x) in 2009 had been grappling with severe depression.

She left the group which became one of the most popular girl groups in South Korea’s pop history in 2015 and launched a career as a solo singer and actress.

Recently, she appeared on a live television programme in which Korean pop stars discussed their experiences.
