Russian police are investigating a sinister ‘game’ spreading on the web instructing children about ‘how to become a fire fairy’ – by secretly turn on the gas rings on kitchen cookers.

The sickening social media scam is created to look like a harmless prank modeled on popular animated series ‘Winx Club: School of Witches’. But children – and it is aimed at young girls – are told that if they turn on the gas burners on their stove and repeat ‘magical words’, they will become ‘fire fairies’.

One little girl, five-year-old Sofia Ezhova, was severely burned after switching on a gas oven while playing the game.

The social media post says: ‘At midnight when everybody is asleep, get up from your bed and go around the room three times, then say the magical words: “Alfey kingdom, sweet little fairies, give me the power, I’m asking you.”
