Car part theft walkley

[budapest 10]

For the second time in less than a month I have had my windscreen wipers stolen from my car while parked overnight on the road outside.  I have also had my aerial stolen this year, and previously had wing mirror casings as well as having had my windscreen wipers taken several times.  I'm getting really fed up of it and wondering if other Astra  (or any other car for that matter) owners in the area are having the same issues.
