Who called from the number +1 (702) 323-5897

Phone number called me, and was very rude. Caller said " What the FU** do you want, and why the FU** do you keep calling me?" I said that I never dialed that number and asked who was calling, the response was.. " FU** YOU AND DON'T FU**ING CALL ME AGAIN!" and hung up on me. I called the number back to try and find out who was on thee other end of the phone....It went promptly to message, which said " This officer is not available to answer your call, if this is a police emergency please dial 911." So I called Las Vegas police too see if I could find out who the cop was with the nasty attitude, they looked in their system and said that they did not use that prefix or number. I then went on been verified and found that the number comes from Search Light NV. and that this number and 4 others belong to cop cars in Search Light NV. I have not been able to get the police department in Search Light NV. to answer my questions about the owner of this number.
