Children have been left upset and disappointed after an art installation in their school grounds based on Norfolk's sea henge was vandalised.

The School Henge structure was put up in the grounds of Burnham Market Primary School in July using wooden posts decorated with copper plates decorated by the pupils.

But last week, children went back to school after the weekend to find vandals had pulled off some of the plates.

It is believed they were stolen sometime between Thursday, Sept-ember 18, and Monday, September 22.

The damage, which is being investigated, has led to police in the Hunstanton and Burnham Safer Neighbourhood Team to appeal for villagers to report any anti-social behaviour in the village.

Headteacher Steven Hales said: “The damage is very disappointing for the school as it was something the children took pride in and spent a lot of time decorating.”

PCSO Paul Linsell said the incident was an example of a small rise of similar incidents in the village, believed to have been carried out by a group of local youths, and that patrols would be stepped up.

“Burnham Market is a safe and quiet village and it is a shame that a small group are committing petty criminal damage,” he said.

Anyone with information is asked to contact the police on 0845 456 4567.
