The man behind a sick 'suicide game' aimed at children has been inundated with love letters from teenage girls addressed to him at a Russian jail where he is in custody.
Philipp Budeikin is being held on charges of inciting at least 16 schoolgirls to kill themselves by taking part in his social media craze called Blue Whale - which police fear is spreading to Britain.
The Russian 21-year-old - who has now confessed to the crimes - says he thinks of his victims as 'biological waste' and told police that they were 'happy to die' and he was 'cleansing society'.
The lethal game called Blue Whale involves brainwashing vulnerable teenagers over a period of 50 days, urging them to complete tasks from watching horror movies to waking at strange hours, and self harming.
Eventually exhausted and confused, they are told to commit suicide, and it is feared in Russia that dozens have done so at the bidding of Budeikin or other 'mentors'.
