Partially, yes. But there was an incident with a man, or men, that led up to that.

The woman, identified as Ahoo Daryaei, had been harassed inside Tehran’s prestigious Islamic Azad University by members of the Basij paramilitary force.

The forces ripped Daryaei’s headscarf and clothes – leading to her staging a protest by stripping to her underwear outside the university.

Personally, I don't think Iran would have released her based purely on international pressure or social media. Protests and condemnation on this topic is nothing new to them
