New South Wales police arrested a French man in Sydney after he climbed to the top of a skyscraper, without safety gear and without permission, media reported.
Alain Robert, known as "spiderman" is famous for climbing tall buildings around the world without ropes or climbing gear.
The Lumiere is a high-rise apartment building in Sydney and stands 57-stories, or 176 metres tall.
"It is pretty extraordinary stuff, I mean the fact that he is climbing without any ropes or any safety gear," said one onlooker.
Media reports say Robert scaled the building in less than 30-minutes. When he arrived at the top, police were waiting for him.
"The New South Wales police look very dimly on this, we had to use a number of different resources here today, obviously been a tremendous effect on the people of Sydney, we have had to close streets etcetera, so we will be prosecuting him to the full extend of the law," Mark Christie from NSW police local area command told media.
Previously, Robert climbed the Petronas Tower in Kuala Lumpur, the Eiffel Tower in Paris and the New York Times building.
