Fearless free-climber documents himself at the top of a 200-metre crane in south London after scaling the structure without a safety rope.

The filmer said: "It was a serious mission infiltrating the site all considering it was active 24 hours.

"I had to start the video at the top of the building because the initial infiltration was too dark to get significant footage.

"I'm so surprised the security guard in the skyscraper opposite to me did not see me."

The terrifying footage was captured in November 2018.

Here I am climbing the tallest crane in South London. It was a serious mission infiltrating the site all considering it was active 24 hours. I had to start the video at the top of the building because the initial infiltration was too dark to get significant footage. But once I started the climb it was one to remember for the rest of my life... I'm so surprised the security guard in the skyscraper opposite to me did not see me.
