Gardaí confirmed that no prosecution will be taken in the case of Christopher Warren, aged 36, from St Teresa’s Gardens in Dolphin’s Barn, Dublin.
Mr Warren was shot at the Royal Canal Bank in Phibsboro on December 28, 2012, and died a short time later. His death prompted a major murder investigation.
A number of people were arrested as part of the garda inquiry but Detective Inspector Francis Sweeney told an inquest into Mr Warren’s death that a full hearing could now be heard.
“A file was submitted to the Director of Public Prosecution and no prosecution was directed,” Det Insp Sweeney told Dublin Coroner’s Court.
Coroner Brian Farrell adjourned the inquest for full hearing on April 6, 2016.
Meanwhile, gardaí revealed that there have been a number of arrests in connection with the death of Benjamin Whitehouse, aged 39, of Ring Commons, the Naul, who was shot dead in Balbriggan in October 2014.
An inquest into his death heard it is being treated as a homicide.
Mr Whitehouse was shot dead on Clonard St in the town shortly after he and his partner dropped their child to St Peter and Paul’s National School nearby.
