At one point, the group of climbers, that appear to be teenagers, walk along the crane’s girders and one member of the group hangs off a girder as his friends take pictures.

In the video description on their YouTube video, the group state: ‘We went on a crane mission […] and climbed up the 50m crane in the Old Court House area of Wallington. Such an epic mission. Freerunning is our life!’

According to Metro, police have seen the video and have warned any potential copycat groups that stunts like this probably won’t end very well.

TNT does not mind admitting that while watching the below video, some people suddenly found their palms had become very damp. Definitely not one for people that don’t like heights…
