Call the police department. It could have been an oversight. You cannot sue the police because they did not give you back your license (ID) after a traffic stop. If your license was suspended, this would be a different story because the officer would have confiscated your license and you would have received a ticket and/or jail but you stated no citations were issued. I do not know where the other member lives however, when you are pulled over, you are asked to produce your license or ID. This is the only way your name can be run through their computer to be certain you do not have any outstanding warrants, etc.
U have to go down to the police station to get it. Don't call cause they are more likely to not give it back. I have a feeling that ur license was suspended. It can get suspended without u knowing it. Hope this helps!:) GOOD LUCK CAUSE YOU'LL NEED IT!!!!!!!;)
If he just forgot to return it the policeman should try to reach you once he realizes. You can call the district precinct and explain, they will get the message to the officer, you will need to inform them what area, street, you were pulled over in your town so they can find the officer on duty in that area.
