Two bronze plaques which were stolen from an RAF war memorial remembering 1,080 men who died in World War Two, have been returned.
Lincolnshire Police began an investigation after the badges for squadrons 12 and 626 were prised off the memorial at the former RAF Wickenby airfield, some time between 24 February and 10 March.
A landlord of a pub in nearby Scampton found them on his doorstep on Monday.
The former RAF base is now a museum.
The landlord of the Dambusters Pub put out an appeal asking for the plaques to be left at the pub.
