Another email chain-letter containing a picture of a dead child and threatening death if the receiver does not pass it on is circulating among schoolchildren.
The email, which states "I will appear tonight by your bed with a knife and kill you", is the second threatening email to be seen bythe Internet Safety Group this year.
Both emails - the other one was circulated in late June - are believed to have been sent by the same person.
The latest email, with the subject line "this is really wrong", gives the receiver five minutes to forward it to 15 people or he or she will be killed with a knife.
Parents are asked to ring the Internet Safety Group, toll-free on 0508 638-723, if their children see the email.
