Gardaí working as part of a joint agency task force have been conducting a number of operations along border counties with the aim of tackling rural crime.
The operation involved An Garda Síochána and the PSNI.
Gardai say searches targeting organised crime have been conducted in the Sligo and Leitrim division.
This has resulted in the recovery of suspected heroin valued in excess of €61,000 at a location in Sligo and a further €7,700 in cocaine and cannabis at a premises in Sligo town.
Gardaí along with officials from Cavan and Monaghan County Council’s Waste Enforcement Departments, conducted a number of coordinated inspections in a variety of locations in that area.
These included licensed scrap yards, car dismantlers and waste management facilities.
In addition, six vehicles were seized under road traffic offences..
Customs officials, along with gardaí in Cavan, Monaghan and Louth made seven detections in respect of marked mineral oil.
They also discovered 1,000 litres of smuggled kerosene and also seized a vehicle for tax offences.
In Donegal, the District Drugs Unit, supported by Customs, recovered a quantity of suspected cocaine and cannabis following a search of a property in the Buncrana district.
In relation to street dealing in Letterkenny, gardai made a number of detections in respect of possession of illegal drugs for personal use.
Detective Superintendent John O’Flaherty said the gardai are acutely aware that rural crime has the potential to cause serious harm to local communities if left unchecked.
He added that together with their colleagues in the PSNI, they were committed to taking a joint approach to protect and reassure communities on both sides of the border.
