Gardaí are continuing to question four men arrested after a seizure of almost €500,000 of cannabis in Dublin yesterday.

A large sum of cash was also recovered during the operation.

The raids were carried out by gardaí from the Surveillance Unit, the Garda Organised Crime Unit and local drugs units.

A kilo of cannabis herb was recovered and three of the suspects were arrested after a car was stopped on the Kylemore road, Ballyfermot yesterday afternoon.

Shortly afterwards a van was stopped and searched on the Clonsilla road.

In that search, 8.5kls of the drug was recovered and the driver, a man in his late 30s was arrested and taken to Blanchardstown garda station.

The biggest haul of the three raids came later when officers found 15kls of cannabis during a follow-up search at a house on Dale Road in Stillorgan.

A large sum of cash was also found when another house was searched.

The drugs are due to be analysed but it’s understood they’re worth around €490,000 and gardaí believe it’s dealt a major blow to the market for cannabis in the capital.
