Gardaí say they believe they prevented another murder over the weekend linked to an ongoing feud in north Dublin, which has claimed four lives so far this year.
Three men were arrested on Saturday afternoon by armed gardaí from the Emergency Response and Drugs and Organised Crime units.
A handgun, balaclava, petrol and two cars, one with false number plates, were also seized.
The officer in charge of the operation, Detective Chief Superintendent Angela Willis, said the arrest of those who are prepared to take life remains a priority.
At around 3.30pm on Saturday gardaí rammed two cars on Lein Road in Artane and arrested the men.
One of the men, in his 50s, has been charged and is due to appear before the Criminal Courts of Justice tomorrow.
The two other men, in their 20s and 40s, have been released without charge and a file will be prepared for the Director of Public Prosecutions.
