Rights activist Maryam Karimbeigi has been arrested by Iranian security forces after they raided and ransacked her mother's home.
Shahnaz Akmali, Karimbeigi's mother, revealed the arrest of her daughter in a video on June 14. Her other child, Mostafa Karimbeigi, was killed in the crackdown that followed mass street protests over the disputed June 2009 presidential vote.
Akmali said the agents took her daughter with them after confiscating her belongings. She has not yet been notified of the charges against her daughter.
Maryam Karimbeigi and her mother have become outspoken defenders of rights for those killed during peaceful protests in Iran since Mostafa Karimbeigi was shot and killed by Iranian security forces during widespread protests following a disputed 2009 presidential election.
Police carried out a similar raid against her in February, but she was not at home when the operation took place.
In April she was summoned to the security office at the Islamic Azad University, Science and Research Branch, to receive an official explanation after she was allegedly expelled from the school while studying for her master's degree in sociology.
