Gardaí have made an arrest in relation to the murder of John Gibson.
The 28-year-old fitness instructor was killed in a shooting at the Citywest Shopping Centre in September 2017.
He was shot while sitting in his car and tried to flee his attacker on foot -- but died at the scene after being treated by emergency services.
A 23-year-old man was arrested this morning and is due before the Criminal Courts of Justice later.
