INDIA-born Nirmal Sagoo and his family are afraid to spend the night in their own house in London's Romford area. Over the last eight years, human excrement and fire bombs have been pushed through their letter box in the middle of the night, concrete slabs have been hurled into their living room and their car splashed with white paint. The assailants, who signed themselves off on the Sagoos' car as 'C 18', are a little-known ultra-right group which launches targeted attacks.
