Mustang Wanted (yes, that is his name) appears to get a kick out of scaring the hell out of people.
The free-climber has made a name for himself after posting a series of jaw-dropping videos online showing him climbing unaided across skyscrapers and cranes.
His latest offering, a compilation of clips, may be his most outrageous yet.
Viewers have been split in their reaction, with some calling Mustang stupid to be risking his life in such a manner, while others were frightened just watching the video from the safety of their home.
YouTube user Rokas Patkauskas declared: ‘Just watching this makes my palms sweaty.’
