From Britain:
"A Sikh schoolboy, who prompted an inter-faith vigil to promote peace, respect and tolerance after claiming his hair was chopped off by racist thugs, invented the story.
The 15-year-old, in tears, gave a graphic description of a vicious verbal and physical attack by four white males who struck as he walked near his home in Edinburgh. His story was widely reported because of its unusually aggressive nature. It is the Sikh tradition for males to keep their hair uncut and not to shave their beard or moustache.....
But it has emerged that he cut off his own hair, punched himself in the face and concocted the story. It is understood he was experiencing personal problems. Sources say that he felt torn between his Sikh values and more westernised ones. They said he had wanted to get his hair cut for some time, but was afraid of the reaction of some members of his family and the Sikh community...."

Interesting how the liars are always immediately believed. It is such a great excuse for an orgy of self-righteousness. Hat tip to Gerald Hartup, who also has previous reports of similar incidents.
