A PRANKSTER has posted footage of himself being sent through the mail — leading to a warning over the dangerous new online craze.
YouTube personality Kel Swann, 24, was taped in a cardboard box before his sisters, Leila and Yasmin, took him to a local Post Office in London to be delivered to their flat.
Kel, who took crisps and drinks and an empty bottle to wee in, filmed himself inside as he was handed over and taken to a sorting office.
In his video, which has had 1.8 million views, Kel ripped a hole in the cardboard and filmed the outside.
He admitted: “It’s so cold. They’ve left me outside. Wait, they’re loading me. These people proper throw stuff around.”
Afterwards, Kel called it “the dumbest thing I’ve ever done. I’m so glad I got away with it”.
Royal Mail chiefs have issued a warning against the Human Mail Challenge, which originated in the US.
A spokesman said: “It is dangerous and those who do it risk serious injury.”
