Around 200 people gathered to watch as Robert, known for scaling some of the world's tallest and best-known buildings without ropes or other equipment, climbed to the top of the Royal Bank of Scotland Tower.

Police closed off a section of the busy street below, causing gridlock. The crowd cheered as Robert reached the top. He then climbed back down, where waiting officers arrested him.

The 46-year-old has climbed more than 70 skyscrapers around the world, including the Empire State Building, the Sears Tower, Taipei 101 and the Petronas Towers in Kuala Lumpur, according to his Web site.

Robert began climbing as a young boy, scaling rock cliffs in the area around his home. His buildering career began at the age of 12 when he forgot his keys and was locked out of his parents' eighth-floor apartment.

Instead of waiting for them to return home, he simply scaled the exterior wall to his home.

Robert continues his climbing career despite suffering from vertigo brought on after two accidents in which he broke multiple bones.

He has been arrested many times, in various countries, by law enforcement officials waiting for him at the end of his climb. The arrests and trials are normally little more than brief formalities and he has always been discharged.
