A teenage girl allegedly made a chilling threat to ‘shoot 400 people for fun’ at her former school after she was expelled over a number of violent incidents.

Alexis Wilson, 18, is accused of making the comment to a colleague at a pizza restaurant in McAlester, Oklahoma, but was later reported to authorites.

Police raided the her home and found a newly purchased AK-47, six magazines and a 12-gauge shotgun.

The heavily-armed teen denied carrying out the threat, telling deputies she “would never shoot up a school” and had simply been trying to convince her fellow employee that not all gun owners are bad people, Fox23 reported .

A police mugshot shows the teen wearing a t-shirt emblazoned with the “Anarchist Cookbook” logo, a 1971 instruction manual for civil disobedience that has been connected with multiple mass shootings and bombings.

It later emerged that Wilson had been expelled from McAlester High School after a number of violent incidents, and had been previously suspended after being caught carrying a knife.

Wilson’s mother was aware her daughter had been saving for and buying the rifle but did not think anything of it as “Alexis has always shot firearms and had hunted”, it was claimed in a police report.

The teen was charged with felony terrorist hoax and is being held at the Pittsburg County Jail on a $250,000 (£200,000) bond. Her next court date is scheduled for Sept. 27.

Randy Hughes, the McAlester Public Schools Superintendent, said has asked for extra security at the high school.

“We’re having school,” Hughes said. “We went through this last year when we had a threat and it’s the same thing — added security, extra police officers.”
