BARCELONA, Spain — A British daredevil just climbed Barcelona’s Agbar Tower after being jailed for climbing The Shard, the U.K.’s tallest building in July 2019. He served half his six-month sentence for the climb.<br /><br />George King took on the Agbar challenge Dec. 5. The 38-story skyscraper opened in June 2005 to mark the new tech district in the city of Barcelona, in Catalonia.<br /><br />All emergency services could do was wait for the Brit, who climbed without safety equipment, to return to ground level, where he was arrested.
