Police are linking the theft of vehicle parts from outside a house in Horbling with a trailer stolen in Folkingham this week.
A bonnet and four doors were taken from a Land Rover Defender parked on a driveway off High Street some time between 11pm on Sunday and 6am on Monday.
During the same period, a wooden trailer was stolen from the front garden of a house in Billingborough Road, Folkingham, which police believe was used to carry away the parts from the Land Rover.
The trailer had no number plate on the back and anyone with information about either or both thefts should call police on 101, quoting incident numbers 42 (vehicle parts) and 46 (trailer) of July 22 respectively.
