Thought I would post this here since it seems to be going around quite a bit (I've gotten two calls so far)...DO NOT CALL THE NUMBER BACK!

Calling back this unknown number may lead to unwanted cell phone charges.

Officials from the Utah Valley Dispatch Special Service District warn against picking up calls from 473-520-9734. The number is from a Grenada and apparently from a caller who claims to be in distress.

Those who call back are charged by the minute. Spanish Fork police and Utah Valley Dispatch reached out to their communities via Facebook and Twitter to warn people to not pick up the phone.

The scam doesn't appear to be new. News reports as far back as 2002 say answering or returning the call can lead to thousands of dollars in cellphone fees.
