A 22-year-old Iranian woman has died days after being arrested by morality police for allegedly not complying with strict rules on head coverings.
Eye witnesses say Mahsa Amini was beaten while inside a police van when she was picked up in Tehran on Tuesday.
Police have denied the allegations, saying Ms Amini had “suddenly suffered a heart problem”.
It is the latest in a series of reports of brutality against women by authorities in Iran in recent weeks.
Ms Amini’s family say that she was a healthy young woman with no medical conditions that would explain a sudden heart problem.
