Donatien Chamchawala used his home as a bomb factory
A bomb-maker was discovered when a schoolgirl looking for her ball accidentally stepped on a trip-wire in her neighbour's garden, a court heard today.
The terrified seven-year-old set off a series of detonators when she tried to get the ball from the house of 'hate-filled' Donatien Se Sabi Bestrualta Chamchawala.
Her parents called police who uncovered a weapons cache and explosives den in his home in a quiet street.
Police said Chamchawala, 31, had a hatred of gays, Jews and - irrationally - black people, and they believed he could have targeted them for attacks.
Chamchawala, of Blackwood, Caerphilly, south Wales, was today detained indefinitely under the Mental Health Act after admitting making and possessing explosives.
Nicholas Jones, prosecuting, said the defendant, 31, was born with the name Andrew Webbe but changed it in 2003. He said he chose Donatien after the French author and aristocrat the Marquis de Sade, who shared that name.
He added: "Bestrualta is an anagram of "ultrabeast" and Chamchawala is a character in Salman Rushdie's The Satanic Verses.
Mr Jones said: 'His neighbours had a family barbecue and a ball went over the wall into his house. 'The girl's father asked if it was alright if the children retrieved the ball and Chamchawala nodded.

'The seven-year-old and her nine-year-old friend went into the garden when there was a massive bang, followed a couple of seconds later by another.
'Smoke was coming from the garden, while Chamchawala calmly walked back into the house. The children were terrified.'
Cardiff Crown Court was told neighbours became suspicious after Chamchawala left doors and windows open during winter months.
Mr Jones said: 'There were often smells of burning but no obvious signs of smoke.
'But Chamchawala would use air fresheners up to six time a day.'
Anti terror police who raided the house in Blackwood, South Wales, found two swords, a sawn-off shotgun, a revolver a machete and a bullet proof vest.
There were also hundreds of pages of documents where Chamchawala expressed his hatred for innocent civilians including Jews, 'Christian cesspit of America' and British National Party activists.

Officers also found literature including the Anarchists' Cookbook, Bazooka: How To Build Your Own, The CIA Book Of Dirty Tricks, The US Army Counter Sniper Guide and material on booby traps and improvised explosive devices.
Hussain Zahia, defending said: 'There's no suggestion of any intention to deploy explosives and no evidence this was directed to anybody.
'He was experimenting in an obsessional fashion.'
Jobless Chamchawala, who lived off benefits, was sectioned under the Mental Health Act after admitting making explosives and possessing a prohibited firearm.
He was sent to the Caswell Clinic psychiatric unit in Bridgend.
Recorder of Cardiff, Judge Nicholas Cooke QC said: 'It's a common misconception those suffering from mental illness may be incapable of planning and sophistication of what they may do.
'I accept you hadn't gone so far as to direct explosives and weapons at individuals at the time this was discovered.
'But the nature of your illness means if these circumstances arose again the risk would be serious.
'I don't know when it may be safe if ever to discharge you into the community but when that day comes it's imperative you're subject to robust risk management indefinitely.
Detective Chief Superintendent Ray Wise, of Gwent Police, said: 'It's clear he has a deep-seated dislike for several sections of the community.
'While we will never know the consequences of what might have happened had we not intervened.
'From his writings he displayed hatred and antagonism to large areas of the community, including homosexuals and black people.
'His motivation for manufacturing the substances isn't clear and, despite numerous interviews, it's still not clear.
'But we have real concerns in relation to his intent.'
