BERLIN (Reuters) - The heatwave sweeping Germany claimed an unlikely victim when a man sleeping on a roof to escape the high temperatures rolled off, suffering fatal injuries, Berlin police said Wednesday. A tenant of the building found the 28-year-old still alive after his 70-foot fall, but he later died in hospital. The man had bedded down with two friends as temperatures neared 30 degrees Celsius (86 Fahrenheit) in the German capital. The friends only learned of the man's fate after being awakened and informed by police. "The man must have ended up on the steep part of the roof and fallen off," said Berlin police in a statement. His sleeping bag remained hanging off the gutter of the tiled roof.
