Police are investigating a series of shed break-ins at allotments off Clarence Street in Lincoln.
Seven incidents have been reported in the last few weeks, where gardening tools have been stolen.
Officers would like to hear from any local residents who may have seen anything that looks odd or out-of-place in the area.
In particular if anybody living in the area, especially those whose properties overlook the allotments, has seen anything or anyone suspicious, or even anything that strikes them as just not quite right, they are asked to contact Lincolnshire Police.
Also, if anyone has had their allotment shed damaged by an attempted break-in, even if nothing is stolen from inside, they are asked to report it to the force.
Shed owners at the allotments, as well as those who have garages or outbuildings at home, are asked to remain vigilant around security and make sure all doors and any windows are locked and secure.
Police say shed alarms are also an efficient deterrent and are available to buy from the force for £6 via their local Neighbourhood Policing Teams.
