Police deny this and claim she is under arrest “suddenly experienced heart problems”. Her family, meanwhile, says Mahsa Amini was healthy and had no medical problems to explain the heart problems.
They were told she was taken to the hospital just hours after her arrest and was in a coma until her death Friday, the family said.
Tehran police said they detained the 22-year-old to teach her about the hijab, a head covering that is compulsory for all women in Iran.
President Ebrahim Raisi ordered the Ministry of the Interior to open an investigation. Several MPs said they would initiate a hearing on the case in parliament.
The case of Mahsa Amimi was met with many condemnations of famous Iranian women and men, including dissidents and other prominent individuals.
The BBC reports that it is the latest in a series of reports of brutality by authorities against women in recent weeks. Some women accused of not following the strict dress code were thus barred from entering government offices and banks.
Many Iranian men and women, including those who support the government, have taken to social media to express their outrage at the very existence of the moral police, which they describe as murderous.
Videos have surfaced online showing police officers arresting women, dragging them on the ground and forcibly taking them away.
Some Iranians directly blame the Supreme Leader for this Ali Khamenei. His old speech defending the role of the moral police and insisting that women must be forced to adhere to a strict Islamic dress code is circulating on social media.
Strict dress codes for women were introduced by Iranian authorities shortly after the Islamic Revolution in 1979, and women have been resisting them ever since, especially in major cities. In some places, they wear the headscarf much more loosely and thus show their hair.
After 2017, when dozens of women publicly removed their headscarves in protest, the authorities tightened controls. Advocates of cracking down on women, who even support flogging, say allowing women to show their hair leads to moral decay and family breakdown, Al Jazeera reported.
