Gardaí have seized drugs, cash, ammunition and high-powered motorbikes during a crackdown on gangs in the city.
12 searches were carried out at homes and businesses yesterday, across Ronanstown, Finglas, Lucan and Castleknock.
€200,000 in cash, and cocaine - with an estimated street value of €20,000 - were seized in Ronanstown, Lucan and Castleknock.
Gardaí say the searches are in relation to the sale and supply of drugs in the Ronanstown and Clondalkin areas.
In Finglas, 174 rounds of ammunition, 3 stolen motorbikes and a small amount of suspected cocaine were also recovered.
Mobile phones, laptops and financial documents taken from the search locations are being forensically examined.

A man in his 40s was arrested during one of the searches.
He has been charged, and is due to appear in court at a later date.
