The four were all charged with possession of a sawn-off shotgun with the intention of committing robbery and the attempted robbery of a Securicor employee.
The Group 4 Securicor security van was delivering money at the time to a Centra shop ATM in the Foxborough estate, Lucan, Co Dublin.
Another person, Garreth Molloy, 28, from Sheriff Street, in Dublin’s north inner city, was fatally shot by gardaí at the scene.
A sixth man has already been charged in connection with the same incident.
The four men were taken to Blanchardstown District Court yesterday morning to face charges under Section 27B of the Firearms Act 1964 as amended bythe Criminal Justice Acts of 2006 and 2007.
The court was told that two of the accused, 23-year-old John Boylan from Foxdene Avenue in Clondalkin, west Dublin, and 25-year-old Derek Hutch from Chapel Farm Avenue in Lusk, north Co Dublin, were already in custody, so there was no bail applications for them.
The two other men, 24-year-old Darren Keane, who is also from Foxdene Avenue, and 29-year-old Gareth Hutch from Drumalee Avenue, North Circular Road, Dublin, were remanded in custody with consent to bail.
The case was adjourned to May 17 to appear before the same court.
