Natascha Kampusch: 'Freedom felt like a cage'

Natascha Kampusch, held captive in a Vienna basement for eight and a half years, has released her second book, talking about the struggles she has faced since becoming free.

She was just 10 when she was snatched off the street on the way home from school.

Now 29, she says the initial taste of freedom was not how she had imagined it would be.
