Gardaí have arrested a man in his 20s as part of ongoing investigations into armed robbery incidents in Rialto and Kilmainham in Dublin on Monday.
Shortly after 12 noon a lone male armed with a hand gun entered a shop in Rialto and threated staff before leaving the scene with a sum of cash.
Moments later a man entered a supermarket & post office in the Kilmainham area and threatened staff before leaving the scene with a quantity of cigarettes. No one was physically harmed in either incident.
In the course of a follow up operation local Detectives and members of the Armed Support Unit searched a house in the Inchicore area this evening and arrested a man in his 20s.
He is currently detained under Section 30 of the Offences against the State Act, 1939 at Kevin Street Garda Station.
A number of items believed to be connected with the robberies were seized in evidence.
During the operation a firearm was discharged when Gardaí were attacked by a dog. One Garda member was injured in the attack and required medical treatment. The dog has been removed for veterinary treatment.
