Gardaí have arrested a man in relation to a murder in west Dublin last year.
Dean Johnston (20) was shot dead on May 25th, 2011, as he sat in a car near his family home on Moorefield Avenue, Clondalkin.
A 23-year-old man was arrested in Co Wexford by gardaí yesterday evening in relation to the murder. He is being held at Lucan Garda station.
Mr Johnston was killed when shots were fired into a rear passenger window of the car in which he was sitting. He was taken to hospital in Tallaght where he was later pronounced dead.
He was a convicted drug dealer and gardaí believe his killing was drug-related.
