During the course of the search of a residence in the county Monaghan town yesterday, a grow house was discovered containing 57 cannabis plants, along with 13 vacuum bags of dried cannabis herb.
The operation was carried out by Monaghan Divisional Drugs Unit.
The drugs seized will now undergo further analysis with Forensic Science Ireland.
