Fresh threats to “shoot up the school” attended by the teenager who was shot dead by police in Perth on the weekend have been dismissed as a hacking incident, with the school insisting there was no threat to students.

The 16-year-old was fatally shot by police in a car park in Willetton on Saturday night after he stabbed a stranger in the back. The teenager, a white convert to Islam, was known to police and had been in a deredicalisation program for two years.
