So locals go into neighbour's gardens at night to abstract electricity?
What do they do with it?
Some people have an odd attitude to things that belong to others (see below). So I can imagine people strolling in to their neighbour's garden to use an external power socket if they don't have one of their own, e.g. to power an electric lawn mower.
But I find it hard to see when they would be doing at night that fitted into this category. I think that is what @ban-all-sheds is getting at.
Where we used to live was terraced houses on a reasonably busy road so most of the, small, front gardens had been paved over to provide for parking. We had an outside tap at the front which had an internal stopcock and we kept it turned off to minimise any water loss if the front tap was left on or got damaged.
One day I heard a noise and looked out to see that the neighbours (somewhat odd people) were tidying up from having washed their cars using out outside tap. We must have left the stopcock on the last time we used the outside tap. So I just turned the stopcock off.
A couple of weeks later I again heard a noise a looked out to see the same neighbours spending a couple of minutes turning our outside tap on and off and being very puzzled as to why there was no water.
They seemed to take it for granted that they were entitled to use it but did not think of speaking to us about it.
