Independent Iranian news sources reported that Mahvash Sabet Shahriari was said to have had her knees injured while under interrogation by officials in Evin jail. Evin prison is often called the "world's worst prison". It has a reputation for its inhumane living conditions, where inmates are subjected to daily whippings, beatings and torture. Former inmates have previously spoken about the barbaric horrors they witnessed while in Evin- including electrocution, rape, torture and executions. [Daily Mail 11 April 2023]

IranWire received an audio file from Faezeh Hashemi, a political activist and daughter of late President Akbar Hashemi Rafsanjani, herself jailed in Evin but briefly released on a leave of absence, spoke about her cellmates. "Mahvash recounts that during an interrogation the interrogator kicked the chair from under her and, since she was facing the wall, her knees hit the wall. Now, they have X-rayed her in prison and told her that the bones in her knees are broken. She is in such a condition, 70 years old, innocent and in prison only because she is a Baha'i," Hashemi said in the recording. People close to Fariba and Mahvash believe that the delay in transferring Mahvash to the women's ward was most likely because of her broken knees, since interrogators wanted to keep it a secret and kept her in solitary confinement until she could walk.
