"We had the number, and police checked the number, and it was Nossal High School," he said. hgl;jhg Credit:Wayne Taylor "The caller engaged in conversation with the receptionist. All he said was, 'there is a bomb in your school'. After she asked him who he was, he said: 'it doesn't matter, you won't have much time', and hung up ... he sounded like an Australian man." Mr Grossek said he had been informed by police that the hoax calls targeting dozens of schools had been linked to Nossal High, and the possibility was raised of a hoaxer hacking into the school's telecommunication service, to make it appear as though the calls had come from the school. Victoria Police spokeswoman Lee Thomson would not confirm reports on the Nossal High School link, claiming only that the investigation into the hoax was ongoing.

Nossal High School principal Roger Page, refused to confirm reports that his school was linked to the bomb threats, saying in response to questions about the allegations: "It's not nonsense, but I can't comment on it." The principal has been advised by the Education Department not to comment while the investigation was underway. Twenty Victorian schools received threatening calls on Tuesday, which were similar to the calls targeting several schools and learning centres across the state on Friday. Emergency management plans were implemented immediately once the calls were made. Students were either evacuated, or the schools were placed in lockdown. It comes as schools in several other states, and in Europe, have also been targeted.

Victoria Police has been investigating the calls, which are not currently regarded as being terrorist-related, while NSW Police says threats made to local schools appear to be hoax calls from overseas. Police in Britain are investigating if the calls to 18 schools, which led to evacuations, were part of a co-ordinated, "false and malicious" hoax that spread to France. Cowes Primary School on Phillip Island was evacuated after receiving a threatening call about 11am on Friday. Rodney McKenzie, assistant principal at the school, told Fairfax Media a receptionist received a "computerised call". Mr McKenzie told Fairfax Media the caller sounded "like a robot speaking".

"It said there was a bomb located in the school in a backpack." Education Minister James Merlino the incidents had caused stress for school communities. "These anonymous cowards will feel the full force of the law," Mr Merlino said. The Education Department would not confirm reports that the hoax calls have been linked to Nossal High on Tuesday evening.
