(TELEGRAPH) — Counter terrorism police in the Midlands are investigating claims that a 16-year-old boy planned to kill the pupils at his school and then commit suicide.

It is believed that officers seized a notebook containing a list of pupils’ names under the heading ‘Must Die’ when they arrested him at his parents’ home in February this year.

The boy, who cannot be named, had also allegedly drawn up a detailed seating plan of classrooms, marking pupils he wanted to kill with a letter X.

Others reportedly had S for ‘Save’ and N for ‘Neutral’ scribbled next to their names.
