The nativity scene in St Peter’s Hill was vandalised overnight (Saturday).
The panel covering the front of the festive scene was pulled down, with at least one of the wooden sections being broken.
David Burling discovered the damage at around 8.30am on Sunday morning.
He said: “I find it hard to believe that someone would take it upon themselves to vandalise what has become a traditional sight on St Peter’s Hill.
“Clearly the work of drunken idiots who have little respect for public property. I hope they feel suitably ashamed.”
The damage was repaired on Sunday morning.
