Children were left crying and traumatised after a school role play in which one of their teachers was apparently shot dead in the playground.
The pupils, aged ten to 13, saw their religious education teacher run across a field and fall to the ground following a loud bang. Some were so upset that they were sick afterwards, parents said.
The stunt was part of a science lesson designed to teach children how evidence is collected in criminal investigations. They were not told it was fake until ten minutes after the event.
Parents said that for some pupils – including a girl whose father was apparently shot dead several years ago – the reassurance came too late.
