Thieves are always on the lookout for open front and back doors. Keep all front doors closed, and do not give strangers entry to the communal stairwell without satisfying yourself that their business is genuine. Similarly, all communal back doors should be kept locked except when access to the back green is required. Lothians and Borders Police are happy to advise on methods of enhancing the security of properties: ring 0131-662 5000.
