The boy from the German state of Saxony-Anhalt and four other friends wanted to take part in a regatta on Sunday. Their rowboat capsized on a dam and was pulled several meters deep. Rescuers were able to save the four of the other boys, but one 11-year old boy remains seriously injured and unconscious in a nearby hospital.
Police issued an erroneous report on Sunday saying the 11-year-old had died shortly after being rescued, but corrected the statement on Monday morning. A police spokesperson said the force is investigating the mistake.
Divers are still searching canal area for the fifth boy, though chances of finding him alive are slim.
