I got this message from them too...really freaked me out until I saw all the other posts. I was so glad others posted so I figured I would pay it forward. Hope it helps someone.

Yes, I just received the exact same message. It was a woman calling with an accent. She said that law enforcement will be at my door immediately. But strangely did not leave a call back number. Said something about "enjoy my life now" then "law enforcement will be at my door shortly.
Not to worry!! The call is from a thief who is probably in India or Pakistan. It is just a way to try to scare you into paying them (extort would be a better word) money. Ignore them.
