When Leon Edwards was nine years old, he moved with his mum and younger brother from a one-bedroom shack in Kingston, Jamaica, to start a new life in Birmingham, England. Four years later, his mum got a phone call at 2am. Leon could her crying. His dad, a gang leader, had been murdered.

Over the next few years - the "darkest" of his life - Leon was himself drawn into a world of gang violence.
