IT Entertainment’s Lee Seo Kyu, a contestant on “Produce 101 Season 2,” was belatedly revealed to have been a victim of assault at the hands of his old group members.

Previously, in September 2016, three members of the group Naughty Boys (formerly known as Pure Boys), Hwang, Jeon, and Yang (only referred to by their surnames), were charged with assaulting their team member Lee Seo Kyu during a time when they were still promoting as Pure Boys, kicking and punching Lee Seo Kyu in the chest and stomach.

It was later revealed that the three members were fined for their actions.

Member Hwang was also investigated by prosecutors for repeated assault of another group member, while member Yang was investigated for threats and extortion of a group member.

Naughty Boys came to be when the group, which had been promoting as Pure Boys, left the agency, dropped the name, and began to work independently as Naughty Boys, which resulted in the group being slapped with civil and criminal lawsuits.
