Thieves tried to break into Plumbase on the Millbrook Industrial Estate on Tuesday night.
Staff discovered the damage when they turned-up for work on Wednesday morning. After breaking through the outer metal layer of the building they abandoned the break in. The culprits caused criminal damage but nothing was stolen from the plumbers merchants.
The attempted break-in occurred between 5.45pm on Tuesday (1st) and 6.45am on Wednesday (2nd), although staff suspect the attempt might have occurred before midnight.
