‘French Spider-Man’ arrested after scaling London’s Heron Tower

French urban climber Alain Robert has been arrested after scaling one of London’s tallest buildings.

Robert climbed the 662-foot (202-metre) Heron Tower without ropes or safety gear on Thursday as police cordoned off the building, closed roads and ushered spectators away.

Robert, known as “the French Spider-Man,” has climbed many of the world’s tallest structures, almost always without ropes or harnesses and often without permission.
