Astro's record label, Fantagio Music, said in a statement: "On April 19th, ASTRO member Moonbin suddenly left us and became a star in the sky.

"Although it cannot be compared to the grief of the bereaved families who lost their beloved sons and brothers, the ASTRO members who have been with us for a long time, as well as our Fantagio fellow artists and ex ecutives, are deeply mourning the deceased in great sadness and shock.

"It is even more heartbreaking to deliver the sudden news to the fans who have supported Moonbin and sent him generous love.

"I am more heartbroken because I know the heart of the deceased who always loved and thought of his fans more than anyone else."

The label also confirmed that Moonbin's funeral will be attended by his friends, family and colleagues.

Meanwhile, local police have suggested that the K-pop star took his own life.

The authorities said in a statement: "It appears that Moonbin took his own life."

The group's hit records include 'Candy Sugar Pop', 'All Night', 'Blue Flame' and 'Crazy Sexy Cool'.

He was also a member of the sub-group Moonbin and Sanha, which released three EPs of their own.
