Drugs, guns and a caged monkey have been found in Finglas.
The animal was rescued from Ratoath Road this afternoon.
Gardai also seized three guns, 500 rounds of ammunition and cocaine and cannabis worth €100,000.
Clothes, worth €3000, were also seized.
Two men in their thirties and forties have been arrested.
A woman in her thirties is also being questioned.
Dublin North West TD Noel Rock said today’s seizure is "down to the diligent work of local Gardaí and their relentless pursuit of all leads locally".
"They have clearly worked hard to tackle crime and once again have managed to take more guns and drugs out of the wrong hands before they can be used to inflict harm", he said.
Dublin Zoo has denied claims it is caring for the rescued monkey.
