Three members from K-pop boy band Ikon - Kim Jin-hwan, Song Yun-heong and Kim Dong-hyuk - are down with coronavirus.
The group's agency confirmed the news on Sunday (Jan 23) and added that they showed cold symptoms on Saturday.
"We will fully cooperate with the health authorities' investigation and take all measures to prevent the spread of Covid-19.
"We will provide all necessary support to protect the health and safety of our artistes," YG Entertainment said in a statement, adding that the remaining three members have tested negative.
Another boy band member, Lee Seung-hoon from Winner, have also tested positive for Covid-19.
"Winner's Lee Seung-hoon was confirmed to have been infected with Covid-19 today," YG Entertainment said on Monday (Jan 24).
According to the agency, Lee - who is vaccinated - conducted a self-test on Sunday ahead of his personal filming schedule, and received a positive result.
Lee's team members Kang Seung-yoon, Kim Jin-woo and Song Min-ho have tested negative.
All band activities have since been suspended.
