The project was nearing completion, only needing planting and replacement of the benches prior to the project being finalised, but significant damage was caused to the site overnight between Saturday evening and Sunday morning (December 14-15).
It has not been confirmed whether this was an accident or vandalism at the time of going to press.
A Rotary Club spokesman said: “There must be people who have more information.
“We would appeal for anyone who has, to let us know for insurance purposes by emailing [email protected]”
