School worker created a bomb factory

A PRIMARY school caretaker waged a letter bombing campaign that targeted organisations across Britain in protest at a “surveillance-obsessed society”, a court heard yesterday.

Miles Cooper is charged with sending seven letter bombs constructed out of party poppers and nails or broken glass over a period of two weeks earlier this year.

When police swooped on his home in Cherry Hinton, Cambridge, they discovered a “bomb factory” in his bedroom with three more devices, “packaged and more or less ready to go,” Oxford Crown Court heard yesterday.
