South Korean K-pop star Moonbin, a member of Astro, died Wednesday, April 19, at the age of 25.

“Moonbin left our world unexpectedly, becoming a star in the sky,” Fantagio wrote in Korean on its official Twitter account.

Without specifying the alleged causes of the singer’s death, the statement asks everyone to “refrain from speculative and malicious reports” so that his family can pay their respects and honor him in peace.
