'French Spider-Man' Scales 660-Foot Building in Germany

It only took Alain Robert 20 minutes to scale the glass building.

Known for scaling some of the world's tallest structures without safety ropes or permission, Alain Robert is at it again. He is known as the “French Spider-Man.

This time he tackled a building in Frankfurt, Germany. It only took Robert 20 minutes to scale the glass structure that stands more than 660 feet tall.

But what goes up must come down.

Waiting for him on the ground were the cops, who seemed less than thrilled with Robert’s antics. By the time he got back down to the building’s awning, two police officers were waiting there for him. 

Robert’s final trip down a ladder led him back onto solid ground and right into police custody. 

The 57-year-old has climbed some of the world's tallest structures, including the Petronas Towers in Malaysia and the world’s tallest building, Dubai’s Burj Khalifa.
