Several joint agency operations involving gardai and the PSNI were carried out along border counties in recent days which led to a number of illegal goods being seized.
The operation, which aims to tackle rural crime, was conducted on both sides of the border last Thursday.
Heroin worth more than €61,000 was found at a location in Sligo, while cocaine and cannabis worth €7,700 was found at another premises in the town after searches targeting organised crime were carried out.
Elsewhere, gardai along with officials from Cavan and Monaghan County Councils Waste Enforcement Departments conducted a number of coordinated inspections at licensed scrap yards, car dismantlers and waste management facilities.
Six vehicles were seized under road traffic offences, detections were made in respect of driving licence/insurance related offences and a number of fixed charge notices were issued.
During another operation, customs officials, along with gardai in Cavan, Monaghan and Louth made seven detections in respect of marked mineral oil, discovered 1,000 litres of smuggled kerosene and also seized a vehicle for tax offences.
In Dundalk, a man was arrested for drug offences after €3,710 in cash and €1,600 of combined drugs were seized.
In Donegal, the District Drugs Unit supported by Customs recovered a quantity of suspected to be cocaine and cannabis following a search of a property in the Buncrana district.
Gardai in Letterkenny focused on street dealing in the town with a number of detections made in respect of possession of illegal drugs for personal use.
Commenting on the operation, Detective Superintendent John O’Flaherty said: "An Garda Siochana is acutely aware that rural crime has the potential to cause serious harm to local communities if left unchecked.
"Together with our colleagues in the PSNI we are committed to taking a joint approach to protect and reassure communities on both sides of the border.
"This operation forms part of our continued efforts to disrupt the movements and activities of persons intent on causing harm in our communities and works to reduce and prevent criminal activity in border areas."
