Such a thing was not uncommon when I worked for a London Borough in the eighties.
The best one ever was when the council repaved about two hundred yards of pavement and the next day a gang of "Workmen" turned up and removed the lot. Everyone who saw them thought they were council contractors still on the job.
A village church a few miles from where I live recently had a large number of its 200 plus-year-old path flagstones stolen overnight.
Apparently they are very valuable as well of great historical interest and all those involved with the Grade I 700-year-old church are rightly very angry and upset at the theft and the damage to some of the remaining flagstones.
Police believe the theft might be linked to a similar theft from another church in the Leyland area.
