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.
The man, wearing just a pair of shorts, lurches forward from the top of the roof – seemingly aiming for the edge so he can propel himself into the pool.
But as the roof’s guttering collapses underneath him, he lands on all fours inches from the pool.
His head smashes against the floor and bounces upwards, before hitting it a second time as he slumps forward.
The clip ends as his friends rush to see if he is conscious.
Horrified social media users rushed to comment on the disturbing footage.
‘We just witnessed a life-changing event,’ wrote one.
‘It looks like he snapped his neck,’ speculated another.
