Today, right in front of Hassan II mosque, we were approached by a man in plain clothes who, speaking only in French, was seemingly trying to make us believe that taking photos is prohibited and that a security camera has captured me taking photos. He grabbed me by the hand and tried to drag me in some direction, repeatedly saying "polis, polis". I was confident he was fake and took his hand off me and told him to go away. He grabbed me again and I had to take his hand off again. Then he proceeded to make a telephone call, while still trying to make us feel arrested, probably hoping to get some money from us. We just walked away and finally be let us go... Later I told the man in the ticket office about this and he just said photos are allowed everywhere.
Anyone else with similar experience?
