A man from South Shields has pleaded guilty to using Facebook to threaten to gun down 200 American school children.
His message led to thousands of children being kept off school.
Reece Eilliott posted the abuse in the months after a high school massacre in America, and it resulted in an FBI manhunt and armed guards in Tennessee's schools.
However, Elliott admitted today that he was the person behind it all.
