Sydney detectives are fed up with daredevils risking their lives in a new "rooftopping" craze, warning they'll take action against anyone illegally accessing high-rise buildings.
Police on Tuesday said they'd recently been called to five CBD incidents and spoken with more than 80 people over alleged rooftopping incidents.
Rooftoppers scale the highest points of city buildings to take pictures and videos of the cityscape, later posting their adventures on social media platforms such as Instagram and Youtube.
Videos posted online show enthusiasts climbing structures, including radio towers, on top of skyscrapers without safety equipment to take the most impressive images.
Detective Chief Inspector John Maricic said police were at a loss as to why people continue to put their lives in danger.
"The risks associated with the activity are high," he said in a statement on Facebook on Tuesday.
"International incidents have seen people die after slipping or falling from buildings."
