GARDAI have seized a massive €5.1m worth of drugs in a raid in West Dublin.
The operations of a major drugs gang have been dealt a huge blow following last night's seizure.
Customs officers and detectives from the National Drugs Unit were involved in the massive operation in an industrial estate in Blanchardstown at 7.30pm.
Eighty kilos of cannabis herb as well as 350,000 ecstasy tablets were recovered.
A 41-year-old man remains in garda custody after he was arrested at Rosemount Business Park.
A source explained: "This was one of the biggest seizures of the last few years. The operation had been ongoing between the two agencies for some time."
Tens of millions of euro of cannabis herb have been seized nationwide across the country this year in dozens of operations.
However, sources say that gardai are surprised that ecstasy has made a "comeback" in recent months.
"This seizure and others like it show that ecstasy is becoming more popular," said a source.
Last month, gardai seized €1.7m worth of ecstasy tablets in north Dublin, but yesterday's haul of tablets is almost double that value.
While ecstasy seizures of this size are rare, the nationwide crackdown on cannabis distribution has yielded finds of major value in recent months.
An increasing number of growhouses in homes and small industrial units are being discovered through intelligence.
In Co Galway in April, cannabis plants worth about €2.5m were found in Tuam.
It came just days after a raid in Kell, Co Meath, in which €1.5m of cannabis plants and herb was seized.
Approximately 3,000 plants at various stage of growth were seized, along with drug-growing paraphernalia, in Tuam.
Drug gangs are now believed to be driving their cultivation systems underground.
In April, detectives discovered a sophisticated growhouse contained in two 40ft containers which had been buried under a mobile home in a remote part of west Cork.
