A teenager was tortured to death by his sister and her boyfriend after they accused him of witchcraft, a court was told yesterday.

Kristy Bamu, 15, drowned in the bath of a blood-soaked flat on Christmas Day 2010 after begging to die in a ‘tale of horror’. He suffered 101 separate injuries as he was attacked with weapons including metal poles, pliers, knives, a hammer and heavy ceramic tiles.

His sister Magalie Bamu and her boyfriend Eric Bikubi, both 28, are accused of beating him to death because they believed he had been possessed by evil spirits.
