Local Gardaí are again warning people to be wary of scammers.
It comes as a number of elaborate scams have come to light over recent weeks.
The Department of Social Protection this week said fraudsters were calling people offering a fake €350 Covid-19 payment and asking for bank details to transfer money.

It says those responsible are using a number similar to that of the Department's helpline, which is leading some to believe it is legitimate.
Separately, The Office of the Attorney General has issued an alert about a scam targetting members of the public.
A caller claiming to be an official may ring them and claim they've been a victim of identity theft - with their ID used for drug-trafficking or money laundering. They may also claim there's a case against them, and a warrant out for their arrest.
The Attorney General's office wants to reassure the public - asking them not to be alarmed, but cautioning them against sharing any personal information.
Meanwhile, a warning's going out to communities in the North about scammers.
Over recent days people alleging to be from Northern Ireland's Revenue and Customs and National Crime Agency have been targeting people. They also claim to be calling from credit card companies, telephone and internet providers and online retailers.
Police in the North say if anyone you don't know calls you and asks for access or remote access to your computer - put the phone down.
Crime Prevention Officer in Cavan-Monaghan Sergeant Mick Duffy has this advice for people who think they've been contacted by scammers:
