Dominic Deville stalks young victims for a week, sending chilling texts, making prank phone calls and setting traps in letterboxes.
He posts notes warning children they are being watched, telling them they will be attacked.
But Deville is not an escaped lunatic or some demonic monster.
He is a birthday treat, hired by mum and dad, and the ‘attack’ involves being splatted in the face with a cake.
‘The child feels more and more that it is being pursued,’ said Deville.
‘The clown’s one and only aim is to smash a cake into the face of his victim, when they least expect it, during the course of seven days.’
