French stuntman Alain Robert, second left, is led into an awaiting police van after he was arrested for climbing a tall building in Sydney, Australia.

Australian police were on Monday waiting atop Sydney's 57-storey Lumiere Building to arrest world-renowned free-climbing specialist Alain Robert.

Office workers applauded as the stunt man known as the French Spiderman tackled his third Sydney challenge and was arrested for a third time.

Last year, Robert was prosecuted for scaling a 41-storey office tower and in 2003 he was charged after reaching the top of the Harbour Bridge.

“It's a wonderful achievement,” Max Markson, Robert's spokesman, said. “He's got superhuman strength.”

Markson said Robert's vertical exploits were to draw attention to global warming.

He has climbed more than 80 tall buildings, including Kuala Lumpur's Petronas Towers, the Eiffel Tower in Paris and the New York Times Building.

Robert began climbing after being locked out by his parents at the age of 8. Rather than waiting, he shinned up the eight storeys to get in.

Robert is likely to receive a stiffer fine than the AU$750 (about R4 900) demanded of him last year. He was told then to recognise that he was a guest in Australia and should respect its laws. - Sapa-dpa
