Tayside Police is urging householders to be on their guard in relation to people who arrive uninvited at their front door and request access.
Neighbours of elderly residents in particular are asked to keep an eye out for suspicious or unfamiliar visitors to their communities and report those suspicions to the police.
Tayside Police would ask all residents to be suspicious of anyone arriving unannounced at their door.
Householders should ensure that doors are secure, even when at home and use a door chain.
They should not let anyone in until they are certain of who they are, or who they claim to represent.
With regard to anyone claiming to represent a business, authority or agency, householders should demand to see their identification.
Bona fide tradespeople, or company representatives will not be offended and will be happy to provide genuine identification.
Even then if suspicions remain, residents should close the door and check with the company the caller claims to represent.
Don’t take the number from the person on the doorstep, but instead check the phone directory or Yellow Pages.
Beyond that, if a householder remains suspicious they should not let the person in and should contact the police.
Tayside Police would also ask neighbours to look out for one another – particularly if they have elderly or vulnerable neighbours - and report any suspicious activity to the police.
Anyone with information that could assist police enquiries should call 0300 111 2222, or speak to any officer.
