Good job just before Ramadan. Jail and deport them so that they don't enter any GCC country for these illegal activities. There must be many others involved as they will work as a gang. A Lot of expatriates involved also in money laundering, they just collect QR here and in a phone call deliver in the local currency in their hometown. If you observe groceries in interior areas like Umm Salal, Al Khor etc etc. you can track them easily, as their contacts are passed on.
