'Spiderman' scales HK skyscraper: Frenchman Alain Robert, otherwise known as "spiderman" for his climbing feats, has scaled a Hong Kong skyscraper to highlight the issue of global warming.

Police arrested Mr Robert at the top of the 62-storey Cheung Kong Centre, but he was later released without charge.

He unfurled a banner during his climb, naming a website that claims to be counting down the number of months left to save the planet from global warming.

Mr Robert scales the world's tallest buildings without safety equipment.
