Hoodfar: How I survived prison in Tehran

Prof Homa Hoodfar is a dual national Canadian Iranian who was held by Iranian intelligence and detained for over 100 days at Tehran's Evin prison earlier this year.

Recalling her time in captivity, she tells Stephen Sackur: "They told me 'you're going to be here 10 to 15 years and by then you'll be dead so we'll send your body back to Canada in a casket'".

They had sought to make her and others cry but they failed in her case because "I had accepted my fate".

As a professor of anthropology she tells how she turned the tables on them and started to observe their methods.
