Police in Derry are urging householders not to admit strangers to their home following reports of a number of bogus callers in the Foyle area.
In a statement, police say bogus callers depend on the good nature and good will of others, and tend to target the more vulnerable members of our society and in particular, older members of the community.
Police in Derry are advising people to ensure back doors are locked before answering front doors, to ask tradespeople for ID, and not to let anyone into their home until they are absolutely sure of the caller's credentials.
People who are vulnerable should ask the caller to come back later and arrange for a friend, relative or neighbour to be present on their return.
Police say genuine tradespeople should carry a photographic identification card, and this can be verified through QuickCheck on 0800 013 22 90.
The statement concludes that neighbours can also play a part in helping protect the more vulnerable in the community. Residents should try to look out for one another and report ALL suspicious activity to the Police immediately.
