The ‘morality’ police in Iran have returned to the streets of Tehran and other cities ahead of the first anniversary of Mahsa Amini's death in police custody.

A video which went viral on Saturday shows Tehran's morality police arresting a teenage girl without compulsory hijab in Gisha neighborhood in the west.

The girl was screaming “I’m not coming with you” as the morality police try to push her into their unmarked van.

People on social media have reacted to the incident saying if Iranians do not pour into the streets on the death anniversary of Mahsa Amini in mid-September, the regime will tighten the noose.

Amini received fatal head injuries immediately after being arrested in Tehran for “improper hijab” and died three days later in hospital. Her death triggered months of anti-regime protests, which represented the most serious challenge to the clerical regime in 44 years.

Famous opposition figure and women's rights activist Masih Alinejad tweeted that this is how the morality police arrested a teenager for not wearing hijab.

“Mahsa Amini was taken away like this, then killed. Where are those journalists who excitedly reported the cancellation of the morality police?”

She was referring to a controversial report by the New York Times last December that said Iran has abolished the morality police. In response, Iranian activists accused western media outlets of disseminating misleading information on behalf of the Iranian regime.

“This is the grim reality Iranian women are subjected to living under the Islamic Regime. Nothing about this is normal. The only solution is regime change,” reads a tweet.
