Gardai searched a warehouse on Belcamp Lane in Darndale, north Dublin, on the morning of 24 January 2018 and found cannabis plants at various stages of growth in what they described as a grow house.[1][2] The plants had an estimated street value of up to 2.7 million euro, pending analysis.[1][2]

The Irish Times described the site as a large-scale, sophisticated operation with plants at varying stages of maturity.[2] A man in his late 50s was arrested at the scene and detained at Coolock Garda station under section 2 of the Criminal Justice (Drug Trafficking) Act 1996.[1][2]
