Thieves smashed their way into eight cars in Skellingthorpe and Birchwood in just one night.
Some of the cars did not have any valuables inside, but the thieves still broke in to take as little as £5 in petty cash.
Lincolnshire Police are investigating the thefts, which were all reported on Wednesday, December 18.
The inspector taking a lead on the thefts has warned against leaving any valuables on show and issued a reminder to make sure cars are locked.
- Smashed Vauxhall car window on Nightingale Crescent – nothing taken
- Volkswagen car broken into on Ivywood Close – two coats valued at £230
- Vauxhall Astra window broken on Harrier Court – £5 in cash
- Ford Focus and outbuilding broken into on Martin Road – wood taken from building
- Hyundai Ioniq on Queens Way – alcohol, wine, wallet and aftershave taken
- Attempted break in on Denefield – nothing taken
- Ford (Europe) broken into – tool bag taken
- Hyundai Santa Fe on Queensway – unspecified items taken
Gemma posted a picture of her smashed window and posted it on Facebook group You’re probably from Lincoln if, where people reported yet more break-ins.
Inspector Nigel Key said: “A majority of these incidents have been as a result of items being left on show in a vehicle.
“There has also been reports of thefts from a vehicle which has been a result of owners leaving their vehicle unlocked.
“Make sure you have locked your vehicle and your windows are closed too, even for short stops.
“Remove your valuables, even bags, jackets, cases and toys have a value to a thief. A jacket could contain cash or cigarettes that may encourage them.
“Any items should be locked away in the boot, out of sight.”
It comes about a week after another spate of thefts from cars in Skellingthorpe from December 9 but it is unclear if the incidents are linked.
