An employee of a cash-in-transit company was carrying a cash box when he was threatened by a man wielding an iron bar.
The man took the cash box and made his escape in a waiting car.
A 20-year-old was arrested and is being held at Coolock Garda Station.
The car used in the raid was found a short distance away, but the cash box is still missing.
