Police across several states have warned Australian mobile users of a text message that threatens death unless $5000 is paid.
NSW Police said they did not believe the text, which was sent to "a large number of people" this morning, poses a genuine threat and that they were investigating its source.
South Australian police said the hoax text read: "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: killerking247@yahoo.com."
"Please delete the message, DO NOT pay any money, there is no need to be alarmed," SA Police said in a statement.
Queensland police added: "It is important that members of the public are not alarmed and understand that such communications are distributed on mass and are not specifically targeting the individual."
NSW Police said anyone who wanted to report receiving the text could contact the Police Assistance Line on 131 444.
