Iranian protesters have demanded "justice" for a woman who was assaulted by anti-riot police, with one officer forcibly grabbing her bottom and then pushing her on the ground. The video, captured on a security camera at the Argentina Square in Tehran on Wednesday, shows police surrounding the woman. When they start to cart her away, one officer grabs the woman’s bottom before she drops to her knees. Another woman can be heard saying that the officers were pulling the victim’s hair as she knelt on the ground. Tehran’s Police Public Relations office has said the incident will be investigated, the BBC reported, but the police provided no statement as to what might have happened.
