Fearless free-climber documents himself at the top of a 200-metre crane in south London after scaling the structure without a safety rope. <br /><br />The filmer said: "It was a serious mission infiltrating the site all considering it was active 24 hours. <br /><br />"I had to start the video at the top of the building because the initial infiltration was too dark to get significant footage. <br /><br />"I'm so surprised the security guard in the skyscraper opposite to me did not see me."<br /><br />The terrifying footage was captured in November 2018.
