Around 40 people protested on Sunday 28 September in support of the campaign by the family of Gary McKinnon to prevent his extradition to the US on charges of hacking into Pentagon computers.
Gary, who is autistic, admits his guilt but states that his actions were part of an obsession concerning supposed cover-ups of UFO activity by the US government.
The protest was organised by the London Autistic Rights Movement, a new campaigning group.
