The prominent Iranian filmmaker and women's rights activist Mahnaz Mohammadi has been arrested by security forces for "unknown" reasons, according to the opposition website Kaleme.
She is believed to have been seized from her Tehran home by the intelligence services of Iran's revolutionary guards.
Her arrest, the second in three years, has not been reported by Iranian state media.
Mohammadi, director of the acclaimed short documentary Women Without Shadows, also contributed to Rakhsan Bani-Etemad's documentary about Iran's disputed presidential election in 2009.
Another women's rights campaigner, the photojournalist and sports reporter Maryam Majd, has also been arrested and is being held in Tehran's notorious Evin prison.
"Maryam was arrested on the eve of her flight to Germany to report a sports event," said a close friend who preferred to remain anonymous for fear of retribution.
These arrests come amid preparations for parliamentary elections that are set to take place next March.
