Gardai are investigating two separate robberies on opposite sides of the city in which masked raiders threatened staff of shops and escaped with cash.
The first robbery happened at the Daybreak shop on Jamestown Road in Finglas at 9.35am yesterday when three raiders wearing balaclavas and gloves ran in armed with large knives.
They threatened staff before escaping with what is described as a small amount of cash.
In an unrelated robbery at 3.45pm, two men entered the Ladbrokes betting office in Killinarden Shopping Centre in Tallaght.
Witnesses said they threatened staff and were armed with a handgun and sledgehammer.
They escaped on foot with a sum of cash believed to be less than €1,000.
No arrests have been made in relation to either incident and no injuries were reported although it is believed staff were left shocked in each case.
