In 2007, Iranian journalist Maryam Hosseinkhah wrote about her imprisonment in Evin because of her writings in support of women's rights. Published on Payvand.com for Change for Equality, Hosseinkhah described visiting the prison first as a journalist and being told by the prisoners of the good conditions, only to be slipped a note that read "Help us! No one thinks about us here."
A short time later, Hosseinkhah was a prisoner herself. An active member of the Campaign for Equality, her bail was set at an impossible $100,000. She wrote about meeting a woman named Leila who had been imprisoned for two years after a beating by her husband, who was also arrested. But while he made bail and went back to a new wife and children, Leila sat in Evin because, as the mother of a child with Down Syndrome, she dared ask for her nafagheh -- the money a man is required to pay for the expenses of his wife and children.
Hosseinkhah's bail was eventually reduced to nearly $5,500 and she was released in January 2008.
In December 2006, Iranian-American scholar Haleh Esfandiari, director of the Woodrow Wilson Center's Middle East Program, was imprisoned for 105 days after her passport was stolen during a robbery and she tried to obtain a new one. With authorities suspicious about her involvement with the program, Esfandiari was accused of attempting to overturn the Iranian government.
She was released in August 2007 after her mother put up her apartment in Iran to make bail. Esfandiari told Wilson's Quarterly that she exercised and composed a book about her grandmother in her head while in solitary confinement for more than 100 days.
Esfandiari, who was 67 during her stay at Elvin, described a cell with a fluorescent light left on 24 hours a day and interrogations about her position with the Woodrow Wilson Center.
"They never threatened me with physical abuse," Esfandiari told the publication, adding that she believes she got fairly humane treatment because of her age. "The way they would threaten me is to say, 'We are not satisfied with your answers, so your situation is going to worsen.'"
"Torture goes on in Iranian prisons," she added. "I was very lucky that I was neither harassed physically nor tortured."
