Evacuation after bomb threat at Black Hill Primary School

UPDATE: The threat has been given the all clear and the pupils are back in class.

EARLIER: Black Hill Primary School has enacted an emergency plan and moved children from the school buildings following a reported bomb threat.

Ballarat police are attending the scene but there is no other activity at the school site at present.

A planned reptile display at the school had to be abandoned as the emergency siren sounded, with the handlers leaving their snakes, lizards and even a baby crocodile behind.

The animals are being stored in fridges to keep them inactive, according to the handler.

In a statement, Victoria Police said the threats had been made at several schools across Victoria.

“Victoria Police is aware that a number of schools across the state have received a threatening phone call today,” the statement said.

Those schools have enacted their emergency management plans as a precaution. 

The calls coincided with threats made to schools across New Zealand.

New Zealand Police said in a statement on Thursday morning that they were "responding to calls of a concerning nature directed to a number of schools throughout the country".

 "We understand the fear and concern that these calls cause, however we reiterate that so far we have not established any actual threat to any school." 

New Zealand Police added that Thursday's calls "may be similar to those received earlier this year, which inquiries indicated originated overseas".
