Got this via email, but not sure if it’s true:
Warning from police: If you see a piece of paper stuck to your back window, just drive away.
Normally, you would walk across the parking lot, unlock your car and get inside, start the engine then shift into Reverse. When you look into the rear-view mirror to back out of your parking space, you notice a piece of paper stuck to the middle of the rear window. So, you shift into Park, unlock your doors, and jump out of your car to remove that paper (or whatever it is) that is obstructing your view. When you reach the back of your car; that is when the carjackers appear out of nowhere, jump into your car and take off. They practically mow you down as they speed off in your car. So now the carjacker has your car, your home address, your money, and your keys!
The email claimed this occurred near Sultan Center Mangaf. In any case, stay safe.
