Try to recollect the events and your standard practice of driving in the past few days that some traffic police man is hiding such a way that u would have not noticed and they will take note of irregularities such as speaking in mobiles, non tightning seatbelts,such and such is like that and will be recorded in their system and message may be automated subsequently to appear in ur mobile on this particular day. If u are very much sure, just try madeenat khalifa and ask for evidences convincing the situation as you believe now that you have not moved out the car on this particular day. Good luck
