Students at Flowery Field Primary School in the town of Hyde, England, found a Christmas-themed crime scene in their classroom on Tuesday.
Children in a northern England primary school were left traumatized after teachers staged an "elf murder" for a holiday-themed writing project.
Eight- and nine-year-old students at Flowery Field Primary School in the town on Hyde, outside Manchester, arrived to find the crime scene in a classroom on Tuesday, according to The Manchester Evening News.
The crime scene featured drops of fake blood and a body outline appearing to look like an elf.
The school's headteacher, Ian Fell, has since said the students were going to play detectives in an "engaging and exciting" writing exercise involving the crime scene.
But parents say their kids were traumatized, with one child having nightmares as a result of the project.
"The idea was an Elf had been murdered by another Elf. My daughter came home and she was absolutely traumatized," one mother, who asked not be named, said.
The mother said the crime scene involved police tape a knocked over table, and blood smeared on another table.
Headteacher Fell, however, said the children were excited by the project.
"Of all of the 90 children who took part, none of them showed anything but full engagement,” he told Manchester Evening News.
He added: "I have been a teacher for 30 years and this is, in my judgment, an appropriate, engaging and exciting thing that children aged eight and nine have done. They have been so up for it. I am really looking forward to see the quality of the outcomes. We are not trying to keep this a secret and we will be Tweeting about the rest of exercise today."
