FRANKFURT, GERMANY - An urban climber known as the “French Spiderman” has climbed a high-rise building in the German city of Frankfurt and now faces a fine for his effort.

It took Alain Robert 20 minutes to scale the 153-meter (502-foot) Skyper building in the heart of Germany's financial capital early Saturday.

Upon his descent from the gleaming glass structure, the 57-year-old was met by German police who escorted him away.

Robert has climbed many of the world's tallest buildings, often without permission.
