Any questions about money or valuables from callers claiming to be members of An Garda Siochána should be considered a major red flag.
Leitrim superintendent Chris Grogan is urging anyone with suspicions of those calling to their houses, to lock the door and ring their local Garda station for advice.
It comes as Gardai in Leitrim are investigating an incident in Drumsna last Friday morning when a man called to the home of an elderly person in the Drumsna area, claiming that he was a Garda.
He was allowed into the house and made off with a sum of cash.
Local Gardaí have also advised people to talk through a window if they feel in any way uncomfortable about the caller.
Speaking on 'Let's Talk' this afternoon, Superintendent Grogan says while these incidents are rare, precautions should be taken:
"A red flag would be if someone starts alleging that there's been a theft in the area, there's money missing, and they want to check if your money corresponds to the amount taken. I think you'll understand that any bona fides member of the Gardaí will not take it as bad manners if someone is reluctant to engage with them, particularly if they're in plain clothes, before they identify themselves. If that necessitates a phone call to the local Garda station to check, that wouldn't be construed as bad manners".
