The 39-year-old, who uses the name Darren, says he was assaulted by Tory politicians at a central London flat.
He also says he was forced to take part in a satanic ritual at the French Embassy and claims to have been abused by Peter Righton, a former member of the Paedophile Information Exchange.
But Darren now refuses to co-operate with the Met or Suffolk Constabulary after his case was dropped following an 18-month probe.
It came after he refused to hand over medical records when he was asked about a history of mental health issues...
Darren now says only North Korea believe his story and have invited him to live out his years in Kim Jong-un’s murderous regime...

Panorama's The VIP Paedophile Ring: What's The Truth? is on BBC1 tonight.
PS 'Darren' has now fallen out with Exaro News, the main pusher of his absurd fantasies.
@ExaroNews just to say your behaviour lately towards me and others has been controlling and manipulative, wrong + morally reprehensible
