Man climbing Trump Tower in New York using suction cups
A man is trying to scale the all-glass face of Trump Tower in New York City using suction cups.
A video recorded by a bystander and streamed online shows police observing the man from an outdoor terrace.
A police spokeswoman said officers responded to the skyscraper on Fifth Avenue in Manhattan but had no further information.
The 58-storey building is the headquarters of Republican presidential nominee Donald Trump's campaign. He also lives there.
There was no immediate comment from Mr Trump's campaign spokeswoman.
Parts of the building, including the terraces, are open to the public during the day.
