Iran says Armita Geravand, 16, bumped her head on a train, but questions abound a year after Mahsa Amini died

Tehran — Iran's government is trying very hard not to face a repeat of the unrest that followed the death of Mahsa Amini, who died in the custody of the country's "morality police" just less than a year ago. But a new case, that of 16-year-old Armita Geravand, has once again forced authorities to deny that officers, this time members of a local force called Guardians of Hijab, were involved in an attack on a young woman for breaking the Islamic republic's strict dress code.

Geravand, born in the western Iranian city of Kermanshah, was heading to school with friends on a local train in Tehran early on the morning of Oct. 1. She and her two companions boarded a subway car but, not long after, blurry security camera video shows her friends, with help from two other women, dragging Geravand, who seemed motionless, out of the train onto a platform at another station.

She ended up in a Tehran hospital.
