School bomb threats - Minecraft war game blamed for hoax
A conflict involving Minecraft gamers is reportedly behind the hoax emails sent to schools today
Around 400 schools have been affected by the hoax and many were evacuated after receiving the terrifying emails.
According to Sky News, the emails were sent following a feud between Minecraft gamers after the Velt server operators claimed their opponents had been acting illegally.
The emails demanded that $5,000 should be paid to an email address within three hours time or the attackers would "blow up the device".
The hoax is believed to have originated from the US.
In a statement, VeltPvP said: "We've been being harassed by a group of cybercriminals that are trying to harass us in any way possible.
"We're extremely sorry for anyone who had to deal with this, but just know it's fake."
