Police are warning residents in Driffield to take measures to make sure their sheds and garages are secure following a series of break-ins across the East Riding.
Sheds on allotments have been targeted in Bridlington, Goole and Driffield.
In a number of cases security lapses have been seized on by criminals, with shed and garage doors being left unlocked or in a poor condition easy to force open.
It is thought burglars are familiar with the relaxed attitude many take towards leaving their sheds, garages and back gardens unlocked and are abusing that knowledge.
The police have launched an awareness campaign called sheducate, giving people advice on how to keep their sheds and garages safe from criminals.
For more information about Sheducate visit the Humberside Police website.
