Said he was officer so and so, agency not specified. Left a message about a warrant for my arrest and that my location was being watched by the cops. Obvious fake with Russkie accent. Called back and left a message telling him what I thought. Like it will do anything.

Like Jeff posted, I got the same type of message on the same day, using my correct full name.  Scared me for a half a minute, I'm 76 years old and it wasn't very funny!  He said his name was Sgt. Max Clinton.   Unlisted phone numbers are not what they used to be.  What a real jerk and I hope he is stopped from calling other people.  I reported the call to my local police station.
