In 2009, Layla Ibrahim told police she had been the victim of a savage sexual assault. So why did she end up in jail?

Sara Ibrahim says that since the day her little sister Layla was sent to prison, her family has been faced with a simple choice: "Do we give up and just get on with our lives, or do we clear her name? And we've decided if it takes the rest of our lives, that's what we'll do – we'll clear her name."
