(CNN) Two high-profile K-pop stars have been sentenced to prison for sexual assault, the latest development in a sex abuse scandal that has shocked South Korea and its music industry.

Singer-songwriter Jung Joon-young, 30, and musician Choi Jong-hoon, 29, were on Friday convicted of conspiring in the sexual assault of a woman who was incapable of resisting, according to the Seoul Central District Court. Jung was also found guilty of filming women against their will and sharing the sexually explicit material to members of an online group chat.

The court jailed Jung for six years and Choi for five years. Both men are also required to complete 80 hours of a sexual violence treatment program.

Allegations of the crimes were first made public in March , in the so-called "Burning Sun scandal." The Burning Sun club, located in Seoul's upscale Gangnam neighborhood, was allegedly the site of bribery, violence against customers, securing prostitutes for VIPs, rape, drug trafficking and drug use, according to the Seoul Metropolitan Police.

South Korean police confirmed that Jung and Choi were among 10 members of the group chat. Jung was arrested several days later, admitting to the charges and apologizing to his victims.
