Gardaí have released two men held in connection with separate murders in Dublin last year.
Gardaí investigating the murder of Pierce Reid (25), who was shot in the head at Lealand Close, Clondalkin, west Dublin, on August 7th, 2009, arrested a 22-year-old man yesterday.
Gardaí believe the killing was linked to a feud between two drug-dealing factions operating in the Clondalkin area. Mr Reid was aligned to one of the rival factions and was known to gardaí.
The suspect is from Clondalkin and was arrested there yesterday morning. He was detained under section 30 of the Offences Against the State Act and taken for questioning to Clondalkin Garda station.
He was released without charge overnight.
Meanwhile, a man who was arrested earlier this week in connection with the murder of Anthony Cannon has been freed.
Cannon (26), of Robert's Street, in Dublin's south inner city, was shot twice in the head at St Mary's Avenue West, off Sarsfield Road, Ballyfermot, last July in an attack linked to a gang feud in the south inner city.
Garda sources said at least 11 rounds were fired. The victim, who was on bail awaiting trial on assault charges, was wearing a bullet-proof vest.
The man, who is in his 30s, was arrested on Monday. A file will be prepared for the Director of Public Prosecutions.
A second man (32) was arrested in Dublin yesterday afternoon in relation to the same investigation. He remains in custody at Ballyfermot Garda station under section 30 of the Offences Against The State Act.
