Armed gardaí have carried out a raid in Crumlin in south Dublin today, seizing money and electronic devices.
It follows the arrest of four men on the M7 motorway earlier this week.
On Thursday, gardaí in Clonroche in Wexford received reports of four men holding up a garage armed with a gun.
No shots were fired and nobody was injured.
During a follow-up operation, a car was intercepted by the Emergency Response Unit on the M7 at the 'Perpetual motion' landmark near Naas and its four occupants were arrested.
Today, armed gardaí conducted a search of a premise in Crumlin today in relation to the investigation.
So far they have found a sum of cash and seized a number of electronic devices.
Gardaí say the search operation is continuing.
The four men arrested on suspicion of the possession of a gun are aged in their 30s, 40s and 50s, and they are still being held at garda stations in Co Wexford today.
