Issuing a police letter of a car damage for the insurance company to repair it

Hi,

My car was hit by another party who was under the influence of alcohol. The incident happened in Sharjah where my car was in paid parking and the other party drove the car to the parking and hit my car.

Now, this has been taken to the court. Unfortunately, I am not able to repair my car nor the insurance company, because they are asking for a police letter which was not provided by the police.

Since it's not my mistake, why the court or the police are not providing me with the police report?

What shall I do to get the police letter?
