The police chief in Mahshahr, a city in Iran’s oil-rich Khuzestan province, says a new restaurant has been shut down because "a woman was singing at the opening ceremony".

Fars News Agency, which is affiliated with the Islamic Revolutionary Guard Corps (IRGC), quoted Farshad Kazemi, the police chief as saying that "following the circulation of a video on social media which showed a woman singing “illegally” in a restaurant in Sarbandar, Mahshahr, an investigation was launched."

Singing by women in public is forbidden according to Iran’s Islamic laws.

"Police officers closed the restaurant after investigating the issue" and "a judicial case has been filed," added Kazemi.

In the last few weeks, numerous reports have been published about police sealing off businesses, restaurants, cafes and even in some cases pharmacies for not observing the mandatory hijab rules wither by employees.

Mohammad Sadegh Akbari, the Chief Justice of Mazandaran north of Iran, announced Sunday that "a pharmacy in the city of Amol was shut down due to improper hijab of a pharmacist."

In a video published on social media, a regime agent warns the pharmacist for not complying with the "mandatory hijab" and the pharmacist in return asks him to leave the premises.

Iranian regime has increased pressure on women for non-compliance with the mandatory hijab in a situation that the country has been the scene of nationwide protests since September 16, following the death of Mahsa Amini in police custody for not wearing ‘proper hijab’.
