Two teenagers, aged 16 and 17, who were arrested in Co Tipperary yesterday after a couple were robbed at gunpoint at their home in Dublin were released without charge last night.
A file is being prepared for the Director of Public Prosecutions.
Two young men broke into a house in Kilcoran Avenue, Clondalkin, in the early hours of Sunday and threatened the occupants with a handgun.
They stole a car and two mobile phones before fleeing from the scene.
Hours later they were spotted trying to steal another car in Templemore, Co Tipperary and were arrested by gardai following a chase.
The car stolen in Dublin was later found burnt out in Tipperary.
