Three men arrested in connection with the investigation into the murders of Darren Geoghegan and Gavin Byrne were last night released without charge.
The victims, who were allegedly involved in Dublin’s gangland feud, were shot last November while they waited in a car in a housing estate in Firhouse.
In a cross-border operation, gardaí yesterday arrested three men in Dublin, with the Police Service of Northern Ireland (PSNI) also making a number of arrests.
A file on the three arrests will be prepared for the Director of Public Prosecutions.
The murder of Darren Geoghegan (aged 26) from Drimnagh in Dublin, and Gavin Byrne (aged 30) from Crumlin, was believed to have promoted a revenge attack which saw Noel Roche (aged 27) shot dead in a car outside the Yacht Pub in Clontarf.
His brother John had been killed last March in Kilmainham during the time of a long-running feud between the two Dublin-based criminal gangs.
