UK blocks 'UFO-hacker' McKinnon extradition to US

­The home secretary said that there is no doubt McKinnon is seriously ill, that she carefully examined the medical evidence and took legal advice, concluding that his extradition would pose such a high risk that he would end his life, which restricts his human rights.

McKinnon, 46, suffers from Asperger’s syndrome. If convicted in the US, he could face up to 60 years in jail.

The case of McKinnon has become the first time the British government has refused to extradite someone across the Atlantic since the existing UK-USA extradition treaty came into force in 2003, The Independent reports.
