Ed Butler explores the secretive and shocking world of Malawi’s 'hyenas'. These are the men hired to sexually initiate adolescent and pre-adolescent girls – some said to be 12 years old, or even younger. It’s a traditional custom that is endorsed and funded by the communities themselves, even the children’s families. We meet some of the victims, the regional chief campaigning to stop the practice, and the hyenas themselves, and ask if enough is being done to stamp out a custom that’s not just damaging on a human scale, but is also undermining the country’s economic development.
