Chainsaw, tick. Terrifying ‘Leatherface’ character, tick. Partially dismembered victim desperately trying to flee? It’s all there.
Arriving just in time for Halloween, this terrifying chainsaw massacre prank hit YouTube just a day ago and has already clocked up an astonishing 1.2m views.
It was put together by uber prankster Vitaly Zdorovetskiy, who publishes all his work to YouTube channel VitalyzdTv (scroll down for a 'behind the scenes' video.)
He wrote: “It’s that time of year again… Halloween… so I decided to team up with Nick Santonastasso to help me pull this brutal prank… This is definitely one of my favourites.”
Santonastasso plays the "victim" in this clip. The teenager has Hanhart syndrome, a rare genetic disorder with symptoms that can include missing limbs.
Far from letting his condition limit his life, the 17-year-old is an online star, inspiring others with his singing musical and sporting skills.
He’s also got a wicked sense of humour and made waves in November when he appeared as a ‘zombie’ scary unsuspecting shoppers at a supermarket near his New Jersey home.
Since then, Santonastasso has also appeared in a viral prank where he terrifies Walking Dead star Norman Reedus.
