Yes go to the Police Dept. at Madinat Khalifa asap and ask for the picture of the car that was in violation. My colleague had a similar experience. He drives a Land Cruiser and the the car in violation as shown in the picture was a Nissan Maxima. The encoder made a mistake in the last digit of the Maxima's plate number. By the way, you said you have checked the MOI site and there is no violation as you have entered your plate number. This is more accurate. The text you received from METRASH may have been a mistake.
