Need Legal Help Bad Situation for Friend

Without knowing the exact address, I am not sure the Police or any other official would be able to help as they would not know where to find her?

If u  know just the  area . U could go there and ask  people   There , maybe know them .   Take a morrocan to search with u . I hope she is ok

I think that I will know the address soon. But I don't know what the reaction of the Moroccan authorities might be. The guy could have paid them off. She tells me that he got her a visa from the Moroccan ambassador and that tells me that he might have influential friends. Plus that is an islamic country. I don't know much about that but what I see on the internet tells me that women are viewed as possessions and that they do not own themselves. But the guy is not muslim as far as I can tell. I don't know if he can block her from leaving the country. Or make it very difficult?

you have to give the address to someone you/she knows here so that they can file a report in a police station. They would pay her a visit and see what's going on. Regardless of religion, the guy can't keep her locked against  her will. Slavery has been abolished in centuries... Let's hope we hear good news soon enough.

If she is really in that situation you should not be asking on this Forum but consult with authorities and explain them all the situation , they have ways to find the location. You have mentioned her as a Friend and what you are doing is not expected from a friend, go and get some official help

Contact the Vietnam Embassy in Rabat.

Thanks for Your thoughtful response. My main concern is making her situation worse by informing the police or other authorities.
I would guess there is some level of corruption there. Also, I don't know much about Muslim countries and how that would be regarded. I think it's likely that women have less rights there. It's hard to say what the man could be telling the authorities or maybe bribing them??
Since I am trying to help and she only has one other friend, her sister and myself; I was hoping someone there might have knowledge of the society that might help point us in the right direction. We are in Vietnam. Her sister could fly there but only speaks Vietnamese. So I am afraid that we must try to find someone who has knowledge of Casablanca and if there is any hope of freeing her.
