I left my iPhone in someone's car and they won't return it.what should i do?

So i got a ride home from a guy who i just met and i left my iPhone in his car.

at first he said he was going to mail it back to me but then I never heard from him and he's not answering my text messages anymore.

should i threaten the police?

You should keep asking but if they still don't give it back then you will have to call the cops
