Devil Child
Something out of a movie: This is the face that meet unsuspecting passerby.YouTube

This is the moment unsuspecting passers-by receive the shock of their lives when they tried to play good Samaritans.

In what could be one of the best pranks ever performed, the victims are left terrified after believing they had come face-to-face with an evil spirit.

At the start of the video a 'lost young girl' can be seen sitting on a bench with her head in her hands sobbing. It is late at night and as the clips progresses well-meaning pedestrians approach her to see if they can help.

But once they get close enough she reveals her 'devil child' features and blood-stained dress. They are then seen running away after the scare.

The prank has since gone viral, with hundreds of thousands of views on YouTube. It is not known where it was filmed.

"Oh please don't ever let that happen in Texas....I dont want to hear of the child getting shot," one commentator said.

Another wrote: "Face it after all the horror movies, running has been trained into us as a first response. It was soooo funny I wonder how long they kept running. :-D"

A third added: "Man, talk about upping the prank. Nice makeup to add effect. I say keep it up. Teach everyone that there's no good deed left unpunished. Funny."
