Fatima Khishhond, who became popular with her Instagram name, Sahar Tabar, became famous after she posted photos resembling what was described as a zombie version of angelina jolie.
Ms Khishvand was arrested in late 2019 for crimes including blasphemy and inciting violence.
But the director of the prison where she was held denied that she had been injured.

Khishvand’s lawyer, Payam Derafshan, wrote an open letter to the Iranian judiciary, which he posted on his Instagram account.
He said that Ms. Kheshwand’s mother informed him that his client had been transferred to the quarantine section of the prison after he had symptoms of the virus.
He added that Ms. Khishvand – who, he said, was a minor at the time of committing the “crimes” – was not eligible for provisional release because her case was still pending.
Khishvand made international headlines when her heavily-edited Instagram pictures spread. Her account has since been deleted.

She has joined a long list of Iranian internet influencers who have fallen wrong with the law.
A teenager was arrested after posting videos of her dancing online. In the same year, an official in the city of Mashhad was arrested after a video clip appeared showing a crowd of men and women dancing in a mall in the city, while six people were arrested for dancing Zumba.
