A Husqvarna red petrol strimmer was stolen from a property in Beck Hill, Tealby, overnight between Sunday August 2 and this morning (Monday).
The suspects came onto the property via the back fields, climbed over the fence and gained access to the shed and garage.
The offenders cut the locks off and took them as well as the strimmer.
It appears nothing else was taken.
