A text message from a self-proclaimed hitman was sent to thousands of people in Australia. It warned them to not contact the police, under threat of death. So naturally they all called the cops and caused a mini-panic.
It's an old scam, but this is a kind of impressive scale. Here's the message:
"Sum1 paid me to kill you. get spared, 48hrs to pay $5000. If you inform the police or anybody, death is promised. E-mail me now: firstname.lastname@example.org"
