Schools across the United Kingdom have been plced on lockdown after at least 12 schools in Devon and Cornwall received a threatening email, along with schools in Durham.
Parents have since rushed to schools to collect their children.
The email threatened to run over and shoot students at 3:15pm as they leave the school premises, and ended with: “The only way out is to go out with a BANG.”
A spokesperson for Devon and Cornwall Police said: “We are aware of a series of malicious communications to schools in Devon and Cornwall as well as across the country.
“Enquiries continue to establish the facts and forces are working together to investigate who is responsible.
“Police take hoaxes extremely seriously. They divert police resources and cause disruption and alarm to the public.”
Durham Police said in a statement: “Enquiries are continuing to establish the facts and forces are working together to investigate the threat and who is responsible.
“We are requesting that parents do not ring the police as we are in contact with the schools to offer advice and reassurance, and to keep them updated on the investigation.”
Daily Star reports that this threat comes just days after more than 400 schools were caught up in a series of hoax bomb threats.
They received emails threatening to detonate explosives on their grounds if cash was not handed over.
