Two men have been remanded in custody after being charged in connection with a hijacking and robbery.
They appeared at a special sitting of Bray District Court last night and will appear in court again at a later date.
The arrests were made after two armed robberies - at a service station in Palmerstown and at a shop in Tallaght - on Thursday morning.
Nobody was injured in either incident.
The car used was discovered burnt out in the Shankill area, where another car was hijacked.
