The representative continued, "Since the members of Underdog have already split up, it's difficult for us to know what is actually going on at the moment. All we know is that Steelo was hospitalized recently for a month because he wasn't feeling well. We haven't heard from him since then."

Seoul's police investigation team cracked down on various bars, clubs, and businesses in the Gangnam district after reports of smuggling narcotics via international mail and luggage bags came in. 19 of 101 suspects have been caught and arrested on April 26.

In addition to Steelo, a famous professional baseball player was also handcuffed.

Police personnel mentioned the idol star claimed he was only doing a favor. Meanwhile, boy group Underdog debuted in 2013, but seems to have disbanded.
