(CNN) Iranian Instagram influencer Fatemeh Khishvand, known as "Sahar Tabar," has contracted coronavirus while in prison accused of blasphemy, according to her lawyer.

Payam Derafshan published an open letter to the head of Iran's judiciary, Ebrahim Reisei, in a plea for clemency for his client.

"Her arrest warrant was issued in October 2018, at the time she was a minor and I venture to draw your attention to this critical issue that she has contracted coronavirus in jail," Derafshan wrote in an Instagram post

Khishvand, who is famous for her radical appearance and cosmetic surgery, was arrested in October 2019, accused of promoting violence, illicit education, blasphemy, insulting the Islamic veil, spreading hatred and encouraging youth to commit corruption.
