A case has been filed against two of Iran’s leading actresses who recently attended a ceremony without the mandatory hijab.

Tehran Police said Afsaneh Bayegan and Fatemeh Motamed Arya, legends of Iranian film and television, will now be investigated by the judiciary. If found guilty, the two women could face harsh prison sentences along with thousands of other protesters since September.

The case was filed after they appeared in public without the headscarf on Sunday night at a ceremony to honor actor Atila Pesyani.

At the ceremony, prominent Iranian cinema star Reza Kianian spoke of women’s right to refuse the headscarf, made mandatory since the Islamic Republic in 1979.

The government has refused to back down on its crackdown against the mass rebellion across the country, several businesses closed down for not enforcing rules imposed by the regime.

Celebrities and footballers supporting the protests have been singled out with businesses closed down, travel bans, bank accounts being frozen and restricting access to communications.

It comes after a wave of famous faces have used their social media accounts to voice their support for the protests that began in mid-September following the death of Mahsa Amini in police custody.

Many other artists and athletes, including popular Golab Adineh, Katayoun Riahi, and Pantea Bahram have also refused to wear the hijab in public and published photos of themselves casting off their headscarves on social media.
