The two men transferred to a motorbike, which was pursued by uniformed gardaí on patrol in the area.
Following a short chase, the pillion passenger fled the scene on foot and was arrested by officers.
The full amount of cash and a firearm was recovered.
The suspect, aged in his 30s, is being held at Irishtown Garda Station.
Nobody was hurt in the incident and gardaí are continuing to search for the second raider.
