Cocaine and cannabis worth €100,000 was seized by gardai following a routine traffic stop in South Dublin over the weekend.
Officers attached to a road traffic unit searched a car in the Rathfarnham area on Saturday afternoon.
Members of the DMR South Division Roads Policing Unit stopped the car as part of a routine check along the Grange Road.
When they searched the car they discovered a quantity of cannabis, which will be analysed, with an estimated street value of €5,000.
A man in his 40s was arrested at the scene and taken to Rathmines Garda Station, where he was questioned under Section 4 of the Criminal Justice Act 1984.
Following from the discovery of the cannabis in the vehicle, gardai obtained a warrant to search a house at Glenmore Court in Rathfarnham.
During their search of the property, gardai say they discovered a further quantity of cannabis and cocaine with an estimated street value of close to €100,000.
The man arrested as part of the investigation has been charged and will appear before a sitting of Dublin District Court this morning.
It is the latest drug bust in the capital following operations in both Finglas and Lucan last week.
In a separate raid last Tuesday, gardai targeting organised crime groups in the Lucan area carried out a joint intelligence- led operation.
A search was carried out of a house in the area which led to a package containing around 12kg of cannabis herb being seized.
The drugs, which have an estimated street value of around €240,000, will be analysed later in a bid to determine their exact value.
The operation involved members of the Drugs and Organised Crime Bureau (DOCB), and the Revenue Commissioners Customs Service as well as gardai from the Ronanstown Drug Unit.
A 44-year-old woman was arrested at the scene and held under Section 2 of the Criminal Justice (Drugs Trafficking) Act 1996 at Lucan Garda Station.
Gardai said that investigations into the Lucan seizure are ongoing.
