Justin Bieber cancels appearance after Samuel Koch is terribly injured during a stunt.

"Just want to let my people in Germany know I won't be on Wetten Dass tonight as an accident has taken place and we all don't think it is right to continue. Please pray for Samuel Koch & his family as we wait and hope for his health and safety. Germany I'm sorry we couldn't perform tonight but some things are more important than putting on a show. We will be back I promise. Thank u" - Justin
