Outraged parents have slammed a primary school for mocking up a grisly child murder scene for a lesson about finger-prints.
Teachers used a bloody mannequin apparently bludgeoned to death by a crowbar to demonstrate a killing to young children.
Some of the pupils at Ramridge Primary School in Luton, Bedfordshire, were Key Stage 2, typically aged between seven and 11.
The stunt was shared on Facebook with the school boasting it was 'another terrible crime scene' for unsuspecting kids to investigate while learning about forensics during Science Week.
Graphic pictures shared on the school social media page shows police tape surrounding a child-sized mannequin wearing a grey school dress slumped over a table with blood surrounding her.
On the table an abandoned crowbar can be seen - apparently for kids to dust for prints.
In another set of pictures the child-sized mannequin can be seen sprawled face down on the floor with a crowbar and what appears to be a mobile phone next to the 'body'.
Outraged parents flooded the post with angry comments condemning the school's 'disturbing' lesson.
Self-professed 'snowflake' Echo Allen blasted the school's decision.
Echo wrote: "What age children is this for please? As a mother my number one job is to protect my children, especially from the world we are in now.
"I give them the tools and information they need to tackle the relevant 'life' issues as they face them.
"So filling children's heads with this seems a bit far-fetched?
"Maybe I'm a snowflake. If so I accept that because I definitely wouldn't want my young children seeing life like scenes of squashed and mangled bodies.
"'What shall we teach the children today Miss Smith? How about colours of the rainbow or about different animals?'
"'No I know, let's set up a scene that looks like babies have been squashed and violently killed in a crash with blood pouring from them.'
"'Yes perfect idea Miss Jones, the nursery children will grow nicely from that'.
"I mean honestly."
Rachel Kelly wrote: "Wtf!?!? Who even comes up with stuff like this for primary school kids?!
"Very disturbing! I feel like your staff need vetting a little more carefully before offering them a job!
"I'd go mad if I found out this was happening at my daughter's school (which it never would!)"
Kelly Brown wrote: "I hope you asked for parents' consent before exposing their children to this kind of learning!
"Which year group was this unnecessary lesson taught to? If it was my child’s year group I will want a full explanation as to why my permission was not sought beforehand."
Zharia Renée Savage wrote: "This is wrong on so many levels."
Bernadette Valentynne Haggarty commented: "This is disgusting and can probably cause more harm than good for the children."
However one commenter seemed impressed by the school's creativity, bemoaning his own less 'exciting' lessons.
Stevie Smallwood wrote: "I’d have loved to do something like this in that school instead of fighting and living in the family/bip room."
Ramridge Primary School said the matter had been passed to their local authority.
Luton Borough Council have been contacted for comment and confirmed they are looking into the lesson.
