Over the last few weeks there have been several thefts from Grantham gardens, and forced entry into empty properties being renovated.
Items taken include garden ornaments, some of which are very heavy, including a blacksmiths anvil. This indicates more than one offender.
Power tools and construction equipment have also been stolen, along with fixtures and fittings either installed or awaiting installation.
Lincolnshire Police say they are interested in two vehicles in relation to thefts of this type - a Red Tata Safari SUV 4x4 vehicl, on an 04 plate, and a White Ford Transit older model Y plate.
