Rosa Bell and her husband Murray say they looked on in horror as the boundary fence was removed, their patio was dug up, shed torn down and trees were chopped away by contractors working for their neighbours.
The dispute was sparked when The Bells applied for an extension to the side on their three-bed detached home in Tadworth in the UK and as part of the application raised concern about an overhanging guttering pipe and garage wall.
But it escalated when Rosa and Murray were visiting their daughter in Australia and they their neighbours claimed a total of 1.2 meters at one end and 76cm at the other end of the garden as their own.
Rosa said the council and police won't take any action and she is left to pursue the matter through civil court.
