Four people are being held in Garda custody in connection with a cash-in-transit robbery in Dublin in June.
The suspects, a woman in her 20s and three men, two aged in their 20s and one in his 50s, were arrested on Thursday.
They are being detained under section 30 of the Offences Against the State Act, 1939, at various Garda stations in Dublin.
The robbery took place on the afternoon of Thursday, June 3rd, outside a post office on the Old County Road in Crumlin.
At approximately 12.15pm a male armed with what appeared to be a firearm approached and threatened an employee transporting a cash box.
The man fled the scene with the cash box and got into a Ford Focus car which subsequently drove at speed in the direction of Clonard Road.
Nobody was injured and gardaí later recovered a vehicle which was then technically examined.
