US President Barack Obama has given fresh hope to an autistic man who is battling extradition to America on computer hacking charges.

Mr Obama pledged to find an ‘appropriate solution’ after David Cameron raised the issue of Asperger’s sufferer Gary McKinnon during his first visit to the White House as Prime Minister.

Mr McKinnon – supported by his mum Janis Sharp, from Brookmans Park, has fought an eight year legal battle to prevent his extradition to the US – where he faces up to 60 years in jail if convicted of computer hacking.

He admits hacking into US military computers in 2001 and 2002 but maintains he was looking for evidence of alien life.
