File on 4 Investigates tells the story of Kasibba – a woman locked up as a schoolgirl in a mental health hospital. She languished there for 45 years - despite not being mentally ill. She was finally freed two years ago after the intervention of a rookie psychologist. Reporter Carolyn Atkinson asks why so many autistic people and/or those with a learning disability, including children, are still locked up and why successive governments have failed to meet their promises to move people from hospital to home.
