At 10:10 pm on the 22nd, there was an accident in which five people, including 23-year-old Aimo, fell to the floor 3 meters below the entrance to a karaoke room on the second floor of a commercial building in Sangchang-dong, Chungju,

Both were transferred to the hospital, but Lee and 39-year-old Song Doo-soo are still unconscious.

The other three people are treated for injuries.

All of them were colleagues at a karaoke party on the day.

When you open the exit door, the bottom is opened so that you can ride down with a sturdy door.

A police official said, "Some of them are believed to have fallen out of the karaoke room and the rest of them have fallen into an emergency exit while drying them."

The police are investigating the incident.
