Gardaí want to reassure Monaghan homeowners over a business that has been calling door-to-door in the area in recent weeks.
Vigilant members of the public have contacted local gardaí questioning the legitimacy of an alarm company, which has been cold-calling properties around Monaghan.
In a post on the An Garda Siochána Cavan / Monaghan Facebook page gardaí say they have made enquiries and they are satisfied "this is a legitimate operator".
Officers also thanked the "vigilant members of the public in North Monaghan" for their calls. They also advise it's "better to be safe!" and ask people to "please continue to remain vigilant" and report anything you believe to be suspicious.
