The family of a British-Iranian woman being held in Iran have appealed for her release.
Ghoncheh Ghavami, 25, was detained after going to a men's volleyball match in June.
She was arrested outside a Tehran stadium where women were protesting a long-standing ban on female spectators at sports stadiums.
Her brother Iman said she was "simply willing to enter the stadium and watch the match."
He said he doesn't know if his sister, who is now reportedly being held in Tehran's Evin prison, is being held under any charge.
The British Foreign Office said it is "following up" the case, adding that the Iranian authorities are "unlikely to grant any consular access."
Women in Iran were banned from attending sports events after the 1979 Islamic Revolution, but some exceptions have since been made.
