Gardaí believe the murder of a man in the north Dublin suburb of Finglas yesterday was drugs-related.
The victim (37), from Cabra, was shot several times in the head as he sat in the passenger seat of his car in Casement Park at around 4am.
An attempt was then made to set the car alight by throwing a flammable liquid at it.
The scene was cordoned off yesterday afternoon, and officers have opened a murder case.
