Four people have been arrested in separate garda investigations into serious crime in Dublin.
Three men were arrested in Finglas at around 10pm last night.
A gun was also recovered.
A fourth man was arrested earlier after gardaí from Blanchardstown recovered €10,000 worth of cannabis.
The investigations are part of Operation Anvil.
Meanwhile, gardaí have recovered a sawn off shotgun, a stun gun, ammunition and a small amount of cocaine during searches of houses in the Greenfort Lawns area of Ronanstown in west Dublin.
No arrests were made and investigations are continuing.
