Mir Hossein Mousavi's brother-in-law is among the hundreds arrested in Iran's postelection crackdown, the Iranian opposition leader's wife said Thursday.
In an interview with Iran's ILNA news agency, Zahra Rahnavard warned authorities against attempting to publish forced confessions by her brother or other detainees.
Rahnavard said her 62-year-old brother, Shahpour Kazemi, a communications engineer, was arrested more than a month ago.
More than 500 people remain imprisoned after a heavy crackdown on protesters, Mousavi supporters and pro-reform politicians and activists following the disputed June 12 presidential election. Mousavi claims to have won that vote and that President Mahmoud Ahmadinejad's victory in official results was fraudulent.
