Very familiar went through it many times. It is why he is not allowed to live with me. If you need to call the police do so. He needs to know that you are willing to do so. I got to the point where i just couldn't stand it. Thank goodness my husband was willing. A lot less tantrums when he knew i had learned. It is hard to stand your ground and you never do it when you could be in danger. Sometimes you need to give consequences from a position of safety. Example i will not give you a ride because the last time you were in my car you were out of control. I am sure others have better ideas but the point is if you let him continue he won't learn. Unfortunately it took me far too long to learn and i am not perfect, far from it.
