Authorities in Iran have been making clear their determination to enforce compulsory hijab on women, according to a media report.
This comes after months of protests demanding an end to the restriction, BBC reported.
A hardline Iranian MP has issued an ultimatum to the judiciary to come up with measures to put a stop to women flouting the rules on headscarves within the next 48 hours, the report said.
The mass protests that erupted across Iran in September last year have largely been quelled for now by brute force.
But some women continue to defy the rules on wearing a mandatory headscarf in public. Videos and pictures posted online show the upswell of frustration and anger with the restrictions is still a potent force in Iranian society.

A video posted this week shows a man throwing a tub of yogurt in the face of an unveiled woman. His action was met with outrage by male and female bystanders, BBC reported.
Protests swept across the Islamic Republic following the death in September of Mahsa Amini, a 22-year-old woman detained by morality police in Tehran for allegedly wearing her hijab "improperly".
The interior ministry announced this week that there would be no retreat or tolerance on the issue. The statement said that the hijab remained an essential element of Islamic law and as such would remain one of the key principles of the Islamic Republic of Iran, BBC reported.
The unyielding rhetoric echoed that of the head of the judiciary, Gholamhossein Mohseni-Ejei, who had recently said that women who do not wear the head covering would be prosecuted without mercy.

Now, a hardline MP has said that legislative measures must be taken to enforce what he called the "divine decree" of the hijab, BBC reported.
Hossein Ali Haji Deligani said that if the judiciary does not not provide such action within the next 48 hours, MPs would put in motion a bill to fill the legal vacuum.
He said it would be in line with a report by the parliamentary cultural commission on "chastity and the hijab", BBC reported.
