The mother of British computer hacker Gary McKinnon has welcomed Home Secretary Theresa May’s decision to block his extradition to the US.
Janis Sharp said she was "overwhelmed" after an "emotional rollercoaster" and she said Mrs May had been "incredibly brave" to "stand up" to the US.
Mr McKinnon, 46, admits accessing US government computers but claims he was looking for evidence of UFOs.
The home secretary told MPs McKinnon was "seriously ill".
A spokeswoman for the US State Department, Victoria Nuland, said: "The United States is disappointed by the decision to deny Gary McKinnon’s extradition to face long overdue justice in the United States. We are examining the details of the decision."
Mr McKinnon, from Wood Green, north London, who has been diagnosed with Asperger’s syndrome, a form of autism, faced 60 years in jail if convicted in the US.
But Mrs May said his was a "difficult and exceptional case" and there was a real risk of him attempting suicide if he was sent to the US.
Ms Sharp said her son could not speak when he first heard of the decision but then he cried and hugged her.
She said: "He felt like he was a dead person. He had no job, he didn’t go on holiday... he felt worthless."
His solicitor, Karen Todner, said it was "a great day for British justice" and his barrister, Edward Fitzgerald QC, said Mrs May had been "brave".
Mr McKinnon’s bail conditions, imposed since 2005, have now been lifted, meaning he can once again use a computer and also access the internet.
BBC legal correspondent Clive Coleman said it was a dramatic decision - the first time a home secretary had stepped in to block an extradition under the current treaty with the US.
Shami Chakrabarti, director of civil rights group Liberty, congratulated Mrs May and said: "It is a great day for compassion and common sense."
Mark Lever, chief executive of the National Autistic Society, said: "We’ve started to raise the profile of the vulnerability of people with autism in the criminal justice system."
Mr McKinnon’s MP, Conservative David Burrowes, said: "It’s a life that’s been given back to Gary in a long dark tunnel that is 10 years. This must never happen again."
But Labour former home secretary Alan Johnson criticised the decision and claimed Mrs May had made a decision which was "in her own party’s best interests but it’s not in the best interests of this country".
He said: "Gary McKinnon is accused of very serious offences. The US was perfectly within its rights and it was extremely reasonable of them to seek his extradition."
American extradition expert Douglas McNabb said the US Attorney’s Office would be furious.
Mr McNabb said he suspected it would ask Interpol to issue a red notice - making other nations aware there was an outstanding arrest warrant for Mr McKinnon in the US - which would mean he could be arrested if he left the UK.

I don’t know about you but I revolt against crowning Michael Brown a “national hero.”
Better the crown go to Darren Wilson who according to the Ferguson Police Report shot Brown in self-defense.
Yet there’s already a bounty on his head.
And the media eats it up.
