A trailer loaded with 15 tonnes of barley was stolen from a farm in South Witham on Tuesday night.
The green Bailey trailer, registration FX09 KUT, was taken from land off High Street. It had some damage to the off-side front and rear corners and the rear-offside mud-flap was missing. Officers with Lincolnshire Police believe the burglars would have needed tractor or similar vehicle to tow the trailer away and it would have taken a considerable amount of time.
Anyone who may have witnessed the theft or seen any suspicious activity, or who has any information about the crime, is asked to call Lincolnshire Police via 101, or Crimestoppers, anonymously, on 0800 555111.
