SIX flat-pack sheds were stolen during a raid on B&Q in Spalding.
Burglars cut security fencing at the Pinchbeck Road side of the Winfrey Avenue store between 8pm on August 28 and 7am the following morning to gain access to a yard.
Police say a vehicle must have been used to transport the brown plastic sheds, but it could have been something as small as a Transit.
Officers are asking witnesses to contact them if they saw any suspicious activity at the rear entrance to the DIY store.
Witnesses can call Lincolnshire Police on 101 and ask for PC Scott McCaig or call Crimestoppers, anonymously, on 101.
Details of the incident have only just been released to the media.
