"French Spiderman" Alain Robert, known for rock climbing and scaling skyscrapers without equipment, just climbed up the 29-story (374 feet) Melia Barcelona Sky hotel in 20 minutes, according to his YouTube channel. We're talking bare hands and no safety harness.
According to AP News:
He was questioned by police on reaching the top, but was released without charge.
The free climber has scaled the world's tallest structures, almost always without ropes or harnesses and often without permission. He also gives motivational speeches.
