Homeowners across West Norfolk have been warned to be vigilant following a spate of thefts from sheds.
Addresses in Lynn, Gaywood and Ashwicken have been targeted over the past couple of weeks, although police have declined to say exactly how many properties were affected.
However, officiers are urging to do more to ensure their property is kept securely.
Inspector Nathan Franklin said: “Most shed breaks are carried out by opportunist thieves, therefore please ensure that you lock and secure your shed and garage.
“In the meantime, I would urge residents to be vigilant and report any suspicious behaviour to police on 101 or call 999 if you believe a crime is in progress.”
Areas where thefts have taken place during the latest spate are said to include King John Avenue in Gaywood and Gayton Road, Ashwicken.
Property including a lawnmower and tools have been stolen during the incidents.
Police are suggesting that items of high value should be stored within the home, rather than sheds, and residents should compile a list of valuable items, containing details of makes and models, plus seriel numbers.
They also suggest fitting two sets of locks to doors with security fixings to the hinges, plus either a weld mesh or a crime shield product to windows from the inside.
