According to a report released Friday by the Iranian Forensic Science Organization, the death of Mahsa Amini, after whose funeral a series of protests swept across Iran, was not caused by blows to the head or other parts of the body.

"The autopsy [determined] that the death was not caused by blows to the head or other vital organs or body parts," it said.

According to the medical examiners, the girl had undergone brain surgery when she was eight years old. "On September 13, Amini lost consciousness and fell to the ground. Her heart rhythm was disrupted and her blood pressure dropped. Ineffective cardiopulmonary resuscitation led to the development of cerebral hypoxia. The patient died as a result of multiple organ failure," reads the report.

According to the official version, Mahsa Amini, 22, was taken to Tehran Police Station on September 13, where she suffered a heart attack due to the improper wearing of a headscarf. On September 16, she died in the hospital. After the incident, Iranian President Ebrahim Raisi called the family of the deceased and said he had ordered a thorough investigation into the incident.

On September 17, the day of Amini's funeral, information was circulated on social media that the girl had allegedly been tortured by the vice police. A wave of protests swept across the country.
