Moon Bin was found unresponsive in his Gangnam, Seoul, apartment by his manager on Wednesday evening. He had not been responding to contacts so his manager went to the K-pop star’s home. Gangnam police have not yet provided a cause of death pending an autopsy, but officials told South Korean news media that it is believed he died by suicide.

The star was found dead in his home in southern Seoul by his manager at around 8:10 p.m. Wednesday night, an official at Gangnam Police Station told CNN. Gangnam police told the outlet authorities believe Moonbin died by suicide and “no signs of foul play have been found.”
