Monaghan is one of a number of counties being targeted at present in a crackdown on TV 'dodgy boxes'.
According to today's Irish Independent, legal warnings against their use are being sent out in seven counties across the country.
The action comes following a crackdown earlier this year which resulted in several dodgy box operators being shut down.
The counties being targeted at present are Mayo, Galway, Cork, Dublin, Laois, Louth, and Monaghan.
The organisation leading the crackdown, the Federation Against Copyright Theft, says it is working alongside gardaí on the matter.
An EU report into illegal internet protocol television (IPTV) in 2019 found that Ireland has the sixth highest use of dodgy boxes in the EU.
