A school in Blackpool will have a "visible police presence" after its pupils were threatened with a mass shooting.
Montgomery High School in the village of Bispham in Blackpool was targeted in a series of Facebook posts threatening to "kill as many people as possible".
In the posts, the alleged plotter praised the perpatrators of American mass shootings and said the gun attack would be in revenge for alleged bullying.
He said: "Nobody talks to me or notices me except when they're calling me a nerd and pushing me around.
"As soon as I tell people I’ve got a gun, I start getting bombarded with messages."
When challenged by another student, he said he was serious about his threat: "You think it's a joke? You'll see bullets, bodies, and blood."
Lancashire Police insisted that "there is nothing to suggest these messages pose a credible threat" but they will still be on site as a precaution.
In a statement they said: "We are aware of the posts on social media concerning Montgomery High School, Bispham and are investigating the source and content of these messages.
