Apparently they sniff for keywords and found hits that lead them to believe that there would be retribution, shooting and suicide. Local police were contacted and shut down the school while they investigated and made an arrest. The arrestee, a 19 y/o man, was released on bail. Not a heck of a lot of details, such as what this person was charged with and on what evidential grounds.
It picked up a posting showing a picture of a gun being held above a scrawled note, which read "tomorrow - last day of school" and went on to mention bullies and "leaving this world".
Of course, they don't explain how they think he could have gotten the gun with England's very strict gun laws or even if the student made the photo. I wonder if it was a Photoshop creation.
