Blackminster Middle School in Evesham, Worcs: “…youngsters, aged between 10 and 13, thought they were taking part in a fire drill when an alarm bell rang and they were ushered out into the playground.

But they were left in terror as a man appeared brandishing a gun and appeared to shoot dead Richard Kent, their science teacher, as he ran across a field.

Following a loud bang simulating a gunshot, other staff involved in the act rushed to the teacher’s aid and appeared to try to resuscitate him.

There was a delay of 10 minutes before weeping pupils were taken back to the assembly hall where teachers explained that the pretend shooting had been laid on as part of a science lesson.” (Telegraph.UK)
