A prankster changed a Google map entry for a Yorkshire school to "prison and hell on earth."
Hornsea School was coming up earlier today on Google Maps as "Hornsea Prison & Hell on Earth."
The entry has since been taken down.
Today the secondary school recommended that other schools take steps to prevent anyone tampering with their map icon.
In a statement headteacher Steve Ostler said their energies were focussed on their students "and putting ourselves on the map by providing the best educational opportunities for them."
He added: "We recommend that all schools take ownership of their Google map icon to prevent any copy-cat behaviours."
