We were heading towards Keshavarz Blvd, not even reaching the middle of the boulevard, when someone approached me and said, “You’re coming with me. The others go.” Shadi and I were looking at him with surprise, and one of the motorists said to him, “Not that one, this one.” They were dressed in civilian clothes (probably security forces) and went towards Shadi. Shadi was shaken up and taken by surprise. Suddenly she was then taken away and kept in a Peugeot car. Me and a friend started to yell, “Where are you taking her?!!” That’s also when Shadi tried to struggle and started to cry for help, pounding the car door. My friend then tried to open the door, and we were pulling Shadi out but an official who was inside the car was grabbing onto her. He was pulling onto her in such a way that her manteau (overcoat) was coming off but one of my friends still held onto Shadi’s hand and her blouse and pants that were once intact started to come off when caught in the car. At that time she escaped. The officials in civilian clothing and also me and my friend were running after her. It was then one of the officials from the opposite side attacked her and was pulling onto her scarf. Shadi was resisting his force when the scarf came undone. Shadi again escaped. This time two other people appeared unexpectedly, one of them carrying a spiral baton. They took Shadi and beat her violently while she continued to resist them. We weren’t allowed to go towards her. By force they had taken her and put her in the car. The official manhandled Shadi and it was apparent that for them, her hejab wasn’t even important!! When they brought her to the car, they didn’t even give her the scarf back. The car turned around and sped away. It’s true that no one, other than me and my friend did anything. Maybe if we were more in number, we wouldn’t have let them take her.
Shadi wanted to give her bag to us when the motorist shouted from afar “Keep hold of her bag!” Everyone became shocked that they couldn’t react. We have never seen an official order or identification from these paramilitary forces and we have no idea who they are.
