Momo: Police warn over horrifying WhatsApp image and its connection to sinister 'game' – but reality is even stranger

Momo – the story and the picture – are utterly horrifying. And that's just about the only thing anyone can know for sure. The story is linked with a bizarre and chilling photo, as well as a series of stories that are just as sinister. The picture is being used by people on WhatsApp who trick young people into extreme behaviour that includes taking their own lives, according to those reports. It has led to warnings from the police, telling children to be careful and their parents to look after them. Many include the image, and suggestions that it has some sort of unknown power.
