Memory Moyo witnessed the horror of her village being burnt and destroyed by President Robert Mugabe's notorious youth militias. She decided to flee Zimbabwe after fighting off several attempts to rape her. In South Africa, she had hoped the income earned from plaiting women's hair would allow her the basics of survival. But now the 19-year-old Moyo says her life in Johannesburg has become "hell on earth" thanks to the South Africa Police Service (SAPS).
