"I was given the 'honor' to temporarily marry young girls before they were sentenced to death."

In the Islamic Republic (of Iran) it is illegal to execute a young woman, regardless of her crime, if she is a virgin, he explained. Therefore a "wedding" ceremony is conducted the night before the execution: The young girl is forced to have sexual intercourse with a prison guard - essentially raped by her "husband."

"I regret that, even though the marriages were legal," he said.

Why the regret, if the marriages were "legal?"

"Because," he went on, "I could tell that the girls were more afraid of their 'wedding' night than of the execution that awaited them in the morning. And they would always fight back, so we would have to put sleeping pills in their food. By morning the girls would have an empty expression; it seemed like they were ready or wanted to die.

"I remember hearing them cry and scream after [the rape] was over," he said. "I will never forget how this one girl clawed at her own face and neck with her finger nails afterwards. She had deep scratches all over her."

Returning to the events of the last few weeks, and his decision to set free the two teenage detainees, he said he "honestly" did not know why he had released them, a decision that led to his own arrest, "but I think it was because they were so young. They looked like children and I knew what would happen to them if they weren't released."

He said that while a man is deemed "responsible for his own actions at 13, for a woman it is 9," and that it was freeing the 15-year-old girl that "really got me in trouble.

"I was not mistreated or really interrogated while being detained," he said. "I was put in a tiny room and left alone. It was hard being isolated, so I spent most of my time praying and thinking about my wife and kids."
