Police are hunting vandals who have sprayed graffiti and smashed glass in two derelict buildings on the old hospital site in Norwich.
The criminal damage in the Ivory and Memorial Buildings on Fellowes Plain, on the old Norfolk and Norwich Hospital site in St Stephens Road, includes damage to part of a building which is listed as a war memorial.
As such, the glass was supposed to be conserved and will now cost a considerable amount to replace.
The latest incident of damage happened between 1pm and 10pm on Tuesday, February 14.
Police say they are also concerned about the safety of people entering the buildings, which are derelict and are very unstable and unsafe.
Officers from Norwich South Safer Neighbourhood Team would like to hear from anyone with information about the damage or who saw anyone suspicious in the area.
Contact PCSO Bethany Paternoster at Norwich South Safer Neighbourhood Team on 101 or call Crimestoppers on 0800 555 111.
