A dangerous social media phenomenon known as 'Blue Whale' is circulating the web.

The game, created by Philipp Budeikin, directly targets children and encourages them to harm themselves. So far, the game has been linked to the deaths of more than 100 young people around the world. Budeikin has since been arrested and is being held in prison in Russia after pleading guilty to inciting the deaths of 16 teenage girls.

Since it's creation in 2013, Blue Whale has used horrifying videos to lure children into the game before psychologically manipulating them. The majority of children were young girls, who Budeikin says were targeted specifically for their vulnerability.
