Gardaí have arrested a third person in connection with the murder of a man in west Dublin in September 2017.
Fitness instructor John Gibson died after he was shot a number of times in a car park at Fortunestown Lane by the Citywest Shopping Centre in Tallaght on September 18th 2017.
He was pronounced dead at the scene.
Gardaí have been investigating whether the death was connected to a gangland feud in the west Dublin area.
Today a 29-year-old man was arrested in connection with the shooting.
He is being held at Tallaght Garda Station.
It is the third arrest this week by Gardaí investigating the killing.
On Monday, a 22-year-old man was arrested. He has since been released without charge and Gardaí said they are preparing a file for the DPP.
Last night, a 23-year-old woman was arrested and was taken to Tallaght Garda Station.
