Cash-in-transit raids are now plaguing the large urban shopping centres as gangs carry out military-style surveillance on deliveries and security firm employees.
There have been numerous raids so far this year; in 2011 the number of such raids rose from 21 to 38.
A well-organised gang in the Finglas area has been involved in at least four cash-in-transit robberies this year.
Its members -- who are connected to jailed gangland figure Alan 'Fatpuss' Bradley and murdered hitman Daniel Gaynor -- are based in the Glenties and Berryfield areas.
Sources say that the gang is responsible for stealing more than €100,000 and is a prime target of Operation Delivery, the specialist investigation set up to target cash-in-transit robberies.
Just two weeks ago, more than €15,000 was stolen in a daylight armed robbery in Dundrum, south Dublin. Two men carrying a hand gun and a knife targeted a G4S security van near the Ballaly Luas stop at around 3.30pm.
Gardai are seeking to question a man described has having 'moobs' -- large man boobs -- in connection with the incident.
