Police will track it, when you did not note the number plate did you atleast see the vehicle whether it was a 4x4 or a saloon? Since you are here for 9 years did you identify the brand of the vehicle and the color? Driver was a localor expatriate? Just with these info. they can easily trace a vehicle. But make sure you give the exact detail and not guessing, as not much vehicles will be there with an identical data.
