Lawyer and human rights activist Shadi Sadr has been arrested and detained by Iranian authorities. According to the International Campaign for Human Rights in Iran, Sadr was walking with friends to Friday Jummah prayers when she was violently confronted by a group of unidentified plain-clothed men. She was beaten with batons after attempting to escape, losing her headscarf in the process. Sadr was then pushed into an unmarked car and was subsequently driven off.

She confirmed in a phone call to her husband that she had been arrested and was detained in ward 209 of Tehran’s Evin prison. Ms. Sadr has long served as a defender of human rights issues in Iran and is a member of the Committee of Human Rights Reporters. A lawyer and journalist, she was the director of Raahi, a legal advice center for women until it was closed down. She founded Zanan-e Iran (Women of Iran), the first website dedicated to the work of Iranian women’s rights activists and has written extensively about Iranian women and their legal rights. She has represented activists and journalists, several women sentenced to execution, whose convictions were subsequently overturned.

Amnesty International has called for the unconditional and immediate release of Ms. Sadr. “This was an illegal, arbitrary and violent arrest in which no attempt was made by the authorities to show identification or provide any explanation for their action,” said Malcolm Smart, director of the Middle East and North Africa Programme.
