Super Junior’s Eun Hyuk, Kyu Hyun, Lee Teuk and Shin Dong were involved in a car accident in early Thursday morning (April 19 – 00.20am).

The accident occurred after they finished recording KBS’s Kiss The Radio show. After investigation it’s believed that one of the left tyres exploded and caused the vehicle to turn upside-down.

Kyu Hyun was the only badly injured member. At the time of writing he is out of critical condition, but suffered multiple bone fractures; the hospital will need a few days to diagnose and confirm his condition.
Get well soon Kyu Hyun.
