“Given the size and weight of the stones, it is not something you can walk down the street with so anyone who has spotted anything suspicious in the area or perhaps vans and pick up truck acting suspiciously then I would ask people to come forward and contact us.”
The bridge has been vandalised before, but this time the stones were taken, not simply damaged.
