British-Iranian Ghoncheh Ghavami, who was detained after attempting to watch a men’s volleyball match in Iran, has been freed on bail, her family says.
Ms Ghavami was freed because of health problems and was staying with her parents in Tehran awaiting a decision by the Court of Appeal, they said.
Ms Ghavami, 25, was part of a group of women arrested after trying to watch the match on 20 June.
Iranian prosecutors have since accused her of having links to the opposition.
Ms Ghavami has staged hunger strikes against her detention, while hundreds of thousands of people have signed a petition calling for her release.
