Shocking footage shows a man smash his face onto concrete while trying to jump off a roof and into a swimming pool.
The risky stunt takes a dark turn when part of the guttering disintegrates under his feet and the Armenian man plunges headfirst off the edge.
He hits the ground so hard that his head bounces.
It is not clear what injuries the man suffered after the horrific accident or where exactly the toe curling clip, widely shared on social media, was filmed.
Before he makes the potentially life-changing jump, one of his friends can be seen casually chatting on a mobile phone.
